Hi. I live on the East Coast and I'm a US Citizen and native English speaker. I've got experience in all the technologies you mention from 2 years to about 12 years. In particular, I've been programming PHP for the past 4 years, I've dealt with all kinds of DBs for the past 14 years, I've dealt with UNIX for 18 years (some free bsd, redhat, centos, solaris), and a few other things. You can contact me on skype at lilspenny.
What I'm doing right now is working part-time from home. The best way to work with me would be to set up a project that's by the hour and I'll bid on it. How much time are you looking for? I like to charge $18 an hour - is that ok? You can obviously drop off anytime. I've been looking for a full time job for a few months and I usually make about $50/hr. If I find a job, then I'd want to wind down my part time things to just a few hours but I wouldn't just leave you hanging and I'd still be around to answer questions and help out.
The best thing to do is probably to hit me up on skype. We can talk about what you're looking to do, how much time and money it might take, and how I might be able to help or how you could use freelancer to help.
