EDIT: This was not meant to be a criticism of whoever built this, but a bit of marketing advice.
As someone who might use a service like this, I would pause before using short-term contract programmers that cost $50 an hour. Consultancies bill out fresh grads at rates considerably higher than that, and if there's any slack time at all between tasks then the elves are being billed out at less than $50/hour. That rate seems more suspiciously cheap than like a good deal.
