While I appreciate that you are looking for developers, the spamming has got to stop. Sending generic email for permanent positions, to a group of contractors is pretty silly if not rude.
Some things about me you should know, as a recruiter:
1. I do contract consulting, and I'm not looking for a permanent job.
2. Relocating to another city is not in the cards...unless it's an absolutely amazing job, and even then it's unlikely. I'm based in San Francisco.
3. Yes, that's my hourly rate. Do remember that I pay for all of my own overhead, equipment, materials, etc.
Please don't bother, if the job doesn't fit this bare minimum.
