what is the average size job that you guys are using this service to bid on? I would assume they must be sizable (>$10k) if it saves that much time. at that point it would seem like the fee being charged is not material to the overall potential profit. I can knock out sub 10K proposals in about 10-20 minutes with excel. I do keep a pretty lean SKU list which helps - i don't need 75 different speaker options and i have heavily negotiated pricing with my primary vendors.
