This looks nice, and 10 bucks a month may be OK for many US based people in your target market, but I feel that you are scaring away many potential users by only giving them 14 days to evaluate, which is really not much considering that everyone is busy doing everything else in their lives. Have you thought about adding a permanently free option, or at least giving people several months? The free account can be quite limited in terms of functionality but at least you are giving people more breathing room to test it out before they have to decide.
