Obviously everything in life changes, constantly evolving, sometimes  for the better, other*times not so much. One such issue which has  undergone immense changes in the last 40 years is little league  baseball, and not only by the improved equipment and coaching  techniques, but the typical day to day operation of youth league  associations.
I remember as a kid playing organized baseball, the 
only  new piece of equipment afforded players was a cap. The association  provided the teams uniforms, which were handed down from the 1 year  older team to the year younger team and so on and so forth down the  ladder.
I vividly remember my mother repairing tears in the  uniform knees and sewing a patch of fabric with a sponsors' name crudely  stenciled on the back of the jersey. If you had a rip or hole in the  stirrups, well you were just screwed because they couldn't be repaired.
I  have no idea what the cost of registration was at that time, probably  $2 - $3 from what my dad remembers, which still wasn't chump change when  wages were $2.25 - $3 an hour, but the 1950s were a time of austerity.
As  society changed and the middle class became more affluent, parental  attitudes changed dramatically and the idea of their boy or girl wearing  a hand me down uniform became quite unacceptable. The chance of  contracting a disease, which was a very weak excuse, but a good scare  tactic, females entering the workforce in droves and the inability of  mothers to sew, all contributed to the changing of little league  procedures.
Baseball associations, attempting to please the  parents, began changing their methods of using uniforms no more than two  years before discarding them, but the only method of financing such a  dramatic change was to raise registration fees.
This method worked  until the inevitable occurred, the fees became too high for the normal  family, especially with 3 or 4 children playing to afford. Many  associations, not too long ago, charged $150 for the first child, $75  for the second and $50 for each additional player. Expectantly, cries of  too many kids not being able to afford to play baseball were heard loud  and clear.
Associations faced returning to the past and begin  reusing uniforms or continue to raise fees, both options ruled  unacceptable, leaving only one alternative. 
Make the Coach responsible for providing uniforms.
If  you play in a wealthy area, where most of the parents are lawyers,  doctors or business owners, locating a sponsor who will foot the bill of  new uniforms is not a problem, as the monies spent are an advertising  tax write off.
However, live in small communities, or in a city  where population cluster vastly outnumbers businesses and the coach will  face a huge financial dilemma. I coached in, what at that time was a  smaller community, so I developed a few ideas for obtaining a sponsor  I'd like to pass along, especially to new coaches.
1. Look  at your immediate ring of friends and co-workers. Do any of them have a  business which could benefit from the exposure of sponsoring a little  league team? If not...
2. Go to the next level with friends  and co-workers. Ask them if they know of anyone who may be interested.  Your co-worker's brother-in-law may own a heating/cooling company he  never spoke of until you asked.
3. Have a team meeting with  the parents and explain the situation. One of the parents may own or  work for a company which may be interested. Send them on a mission to  help find a sponsor, also dropping a hint the money may have to come  from them if no sponsor is found.
4. If you're not a  salesperson this may be difficult for you, but you must meet face to  face with business owners in town to request their help. Letters, no  matter how eloquent, will end up in file 13. It'd easy to say "no" to a  letter, not so easy to a face to face meeting.
5. Begin  early!!! I can't stress this enough. Begin searching for a sponsor  immediately after New Years eve. Christmas time is too hectic and  believe me March is too late.
6. If a person says come back  in a week or two... come back. They may have no intentions of helping  and are just trying to get rid of you. However, they may have wanted to  talk to their tax advisor first before committing. Don't stop looking  during those 2 weeks.
7. You may need to get 2 sponsors to  split the cost. Unions are usually quite willing to offer financial  assistance to youth associations, but are normally limited by law or  by-laws of the amount they can contribute. Present a written request to  the union hall spelling everything out in detail and requesting any  funds possible. In my experiences, if they OK the request, they will  automatically contribute the maximum.
8. Last but not the  least, you may have to consider a team fund raiser. There are countless  methods available for teams to raise money, such as car washes, bake  sales, donation buckets and etc.
I found selling candy bars to be the 
Easiest  method to raise money. Between friends, neighbors and co-workers it  normally doesn't take long to get sell the entire inventory. There are  numerous companies which will work with you in setting up a program, but  be careful of scammers.
