this is pretty cool, personally I'd part with 10% to only deal with vetted clients and be paid on time.
Minor point - I think the min width of your layout is too large (Chrome). Especially with the right justified navigation, I didn't even see the last two links and on the home page I've got to do some side scrolling.
One that I can't get out of my mind - but it's more enterprise-y and not very 'sexy':
Enterprise software selection is a mess - often involving a team that doesn't know much about technology, the landscape of vendors, how to go about actually selecting the best vendor for the requirements, contract negotiations, etc. I've run several of these for a bunch of organizations from Fortune 10 to small non profits, and generally the steps are the same. Create a high level scope, create a 'long list', gather and prioritize requirements, allow vendors to respond, score and rank responses, demonstrations, short list, negotiations, selection. The details may vary a bit, but to me that seems like something that could be automated, with an app that would guide the team through the process relatively easily. Over time you could even build a library of requirements, vendors, and vendor responses (assuming you could manage the ownership of these artifacts).
