Ongoing work for Opencart Websites (Have Template)

I own a few online websites and am after a developer to help me open more. I have the template already, so basically the main of the work will be setting each new store up with the datafeeds properly (usually XML or CSV) and the template. There will be other things like aligning, custom bits for each feed as each will have different specifications etc. I am after someone GREAT, someone I can work with LONGTERM. someone who replies quickly to emails and works quickly and professionally. At the moment I have 5 finished shops and I plan to open around 20 by end of next year, so the work is there if you can prove yourself. Please don't bid if you're a beginner or outsource.. Only quality please, someone who does the work themself rather that in a team. Thanks (We can negotiate hourly rate depending how good you are)
