I don't know if you meant this literally but I couldn't find any mention of price ( just the "contact for trial" language which usually translates as "a lot").
Did you find any explicit mention of pricing ?
In the section "get pay to test", you can read users are being paid 10$ for each answer of an average of 20 min
Thinks for the link, I looked at usertesting but it seem for bigger company base on the price
