Judging from your sites, I doubt you'd need much assistance. Add in the great support for questions here and it shouldn't take more then a few hours to get them over.
The content is quite easy to port over. The style and templates takes a bit of getting used to, but compared to MT, its more like unlearning it, then learning anything new.
Since its all php based and really just one file to edit. You can do all the style and layout in your HTML editor of choice...
If you are really interested in having someone to pay to do this for you, well, I'll help once I know more of the scope of what you want done. However, I think you can easily do the move without paying anyone.
Just set up a test install of WP 1.2 beta or a nightly, do an export out of MT, import it into the new install of WP and play around till you get it right. Once you are ready to switch, there are some other quick hints if you search or ask here to make everything easy.
