The site looks good, one thing I'd call out on the main page is if/how you segment. Can you get the right demographic for a given site or is it just whoever signs up? For more user acquisition I'd try some verifiable claims - "80% of sites who do user testing and iterate on it see an increase in site signups" etc. Also try reaching out to VCs and incubators to get in front of their companies. You might be able to send their email lists an offer for the first 3 companies to get free testing and then all the other companies that respond hoping to get a free test can be upsold to buy. Also attend meetups where startups are presenting and ask about how they use user testing and hand out business cards with a discount code on the back. Set up a twitter and quora search for relevant terms and respond to people's questions/threads and make sure to mention that user testing is a service you provide. Those are all good starting points, if they're not working then the problem is probably the sales person.
