In my humble opinion, the very first piece of equipment you should buy is a first aid kit.......... make one up from scratch in a small plastic tackle or tool box....no rust!
I do not think it would be a good idea to fund raise for individual needs....you are opening yourself up for a lot of conflict...such as having parents up in arms over who is more deserving......kids upset because he got so and so and i did not.....
Many good lists on the net as far as equipment for your troop.....tents,ground clothes, stoves, lanterns, cook kits.............much of which you could put together any any good flea market.......
I admit i do not know much about LDS and what fundraising is allowed.... but fundraising every week is a bit out of ordinary.... try maybe once every quarter according to the seasons for example.....holiday greenery in the winter....... spaghetti dinner in the fall etc.
As far as CC our district offers committee chairman training...............also check with your local area troops to see if they have gently used equipment that they may want to part with
