Boy Scout Eagle Project kiosk at DTE Energy Trail

I am raising money to fund my Boy Scout Eagle Project. I will be using the money to purchase materials to build a kiosk as the new McClure road parking lot at the sugar loaf loop of the DTE Energy Foundation Trail. The kiosk will be wooden with a shingle roof. When finished it will be approximately 12'x10'. My project will allow the DNR to post needed information for those who are using the recreation area. It will have directions to nearby attractions, rules for use of the rec area, trail maps, trail rules, and other information. This will help people understand the safest way to enjoy the park and trails, while also giving them ideas of where else in the park to visit in the future. I need to raise $500 to buy the supplies by the end of march. materials include 4x4 beams and 6x6 posts to make up the body of the kiosk, 4'x'6 plywood for the sign and several 6x10 roof boards, screws, bolts, nuts, and nails to hold everything together, roofing felt and shingles as well as roofing nails. Finally I will need concrete to hold the kiosk in place.
