I think its good you have a business model, but I think you're price points are little high. I would put one option out there as free. With a 14 day trial at $40 a month, to me is very high. I wouldn't even go through the 14 day trial, as you have a lot of competition in this space. More than likely someone using this type of product is not someone that will want something that complex. Theres wufoo, google spreadsheets, formstack, all offer a free option. Good luck
