10 months is a long time... you could try to hire non-rails experts and then train them...?
I'm under the impression that it's not only recruiters but also companies who try to hire people with the exact amount of experience for the position; but a good Python dev can certainly pick up Rails fast, no?
We are open to that. At the moment the source of resumes has been recruiters that were given a certain set of marching orders. It might be worth updating those.
