Nobody's posted here for a little so...
My troop has about 5 fundraisers a year. We are only a small group of 12, with 4 adult leaders.
We have fundraisers that sound difficult but are extremely simple.
We do two clothing drives, two craft shows/flea markets, and an easter bunny breakfast.
The clothing drives are extremely simple to do. You schedule a meeting with a company who pays per pound of clothes. My Troop has made 1000+ from it once. It depends on how many donate, so advertise well. Invest in yard signs, papers in public business, etc. You unload their car, give them a tax receipt, and they're on their way. It is extremely easy, especially for a small troop.
Flea Markets... not completely easy, but as long as you have a team of people with experience in fundraising. If you do have one, do not call it a flea market, call it like "Holiday Bazaar", "Craft Show / Flea Market", something to appeal to others. Flea Market means to some people garage sale junk.
Breakfasts are really simple, have three-four parents in the kitchen (use your charters space if possible) and then buy in bulk pancake mix (you can make waffles with it too) and have scouts wait around the tables. Buffet style can cost you more money, offer two pancakes or one waffle, drink, and a piece of sausage.
If you have any questions feel free to ask!
