Jim has finally bitten the bullet and converted to movable type. He seems to be quite pleased with the results, and it certainly looks and behaves much better than before. Check him out if you haven't already.
Having sub-blogs is actually pretty straightforward with MT. It never ocurred to me to offer a similar service, but if anyone out there is interested use the "tell us about it" widget on the left and we can talk.
I also do full-blown site setup (see valvt.com), but I do charge a bit of $$$ for that sort of thing (although my rates are very reasonable!) Again, if you're interested, use the widget and I'll get right back to ya.
