Great idea!
Personally I don't think "Sound good?" is the right text for a button and making potential users click a button only to scroll down and need to click another button is probably going to mean losing some users in that extra step.
Generally I think your landing page needs some work. I've heard pg say in a couple places that you need to make sure every single word on your home page is there for a reason. Make sure every button takes users closer to where you want them to be (paying you I assume).
Maybe just take a look at the homepages of all the YC startups' home page - this should help: yclist.com/
Also it might be more impactful to give examples of how people used your app instead of testimonials.
One more idea: maybe play around with the pizza delivery idea of "if it's not there in 39 minutes, it's free". So what i mean is I post a question and the price I pay for the answer decreases, the longer I wait for the answer
