Metronicity

I have a blog hosted on squarespace.com. It has rather a lot of content - 500+ pages/1400+ posts including video. I want to put it on a Wordpress template and move it across to my Hostgator a/c. I've had two people contract to do this at $35 and both have stuffed it up. The first gave up after half-way. The second nearly finished but moved it to the wrong domain and none of the posts were in chronological order. The first took a month and the second a week - after quoting one day for the job. So I need someone who knows what they are doing, is reliable, has a good track record, good testimonials AND can speak and write English fluently. PM me and I'll give you a link to the site before you quote. The site in question is very important to me - it got 506k unique visitors in May.
