Mark im sorry to see your not getting more response on this subject. i will just give my thoughts for what they are worth. i would first figure what you need as far as equipment then go direct to manufactures and see what they can donate even if it is just a discount. also try retailers like walmart & sams club usually mangers have it in there budget to donate products or discounts. im sure if you just call a lot of people and tell the story eventually someone should be able to get you something. also this may seem a little silly but around now a lot of radio shows and companys do those christmas wish type give aways for people in need that may be something else to look at.
Good Luck
Jake
