Speaking as someone who occasionally hires people off of odesk, I've learnt to basically ignore any bids that come in the first few hours and give it at least 3-4 days before starting even to seriously evaluate candidates. I don't see how being the first bid vs the seventh bid should affect your chances of getting the job.
Everyone wants you to review them with 5 stars because anything less is bad for business. The quality does greatly vary and so does the pricing. You can get good deals and you can get burned. I once had someone using a keep-active program so they could log more hours. Thankfully I looked close enough at the screenshots to notice.
If anyone can recommend a great mobile designer on oDesk, I'd like to redesign my iOS app: https://itunes.apple.com/us/app/h4-spanish-lite/id388918463?...
My account on oDesk is h4labs, not sure how to link to it.
