I have to start by calling BS on the claim made by another poster that paying less than $100/hr for offshore developers poses a 'risk'. That is beyond laughable, for two reasons, and even what some would consider the 'gold standard' of high-quality and high-quality-control, Toptal, rarely charges as much as $100/hr (and certainly not to us!).
Firstly, I've found no correlation whatsoever between the price paid to developers and the value/quality of the work done in return. I've had very high value from developers costing less than $20/hr, and very low quality/productivity and of course, abysmal value, from developers costing way over $50/hr.
At one time, we decided to go 'wild and crazy' and get a $100/hr guy on board. Utter disaster. Almost as disastrous was the $50/hr guy.
Steve Jobs once famously said there was a ten-fold difference in productivity/quality/value between good and bad programmers. The problem is - for us all - in finding the people at the high end of that scale, and money is not a measure.
Secondly, the whole concept of off-shore developers is 'we can profitably provide comparable services to those offered by local developers, at massively lower cost to our clients, because we have a lower cost base to start with'.
Sure, developers and their employers are as greedy as the rest of us, but when in India you have developers earning $5 - $20/hr, even the greediest company doesn't need to rebill that at $100. When you have developers in E Europe earning $10 - $30/hr, the same metric applies.
And when the going charge-out rates for offshore developers seem to cluster around $12 - $30 from India, and $20 - $50 from E Europe, there's just no commercial ability for contracting companies to charge $100+ and get business. Other than, apparently, from Mr Owens.
TL;DR : Don't judge the quality of your potential contractor by their cost. The only thing that happens if you pay over $100/hr is that you blow through your budget three, four, five, or even six times faster than you need to.
And now as a reward for those who have read this far, a recommendation. My company has used way too many different contractors, all around the world, but at present, we are very comfortable with a Ukrainian company, Active Bridge.
There are a number of reasons we like them, and I'm happy to talk more on that topic if desired - reach out directly, perhaps. But I'd suggest you reach out to Eugene Korpan - (his email was 'removed to protect privacy' - thanks, Founder Dating - but you can find contact details from their website) and see if they can help.
They do specialize in Ruby/Rails, which might limit their appeal. And I'm not sure how much additional workload they can take on at present. Their hourly rates are somewhat negotiable, depending on the nature of your project, and certainly, for us, are extremely competitive.
