I have never raised VC money for anything. However, I think this list contains a lot of good advice for any time you are requesting bids for some service or product. I am on the board of a large cooperative housing organization and we have multi-thousand dollar bids all the time for various repair and maintenance tasks we need completed (and which are outside the scope of what the members can do). Keep your cards close to your chest, don't spread who is bidding what, and most importantly shop around for multiple bidders.
