It's cost over 300 quid for the full company pack (paperwork for everything) but it's all go - now I get to blow a few grand on getting contracts and NDAs drawn up. Funny that lawyers are even more expensive than accountants. Sigh. At least the bank likes me, and I've got leads on some potential investment capital (there's a media government agency that's branching into games in the East Midlands that might be useful). Once the incorporation's finished I can approach them and see what I can get - apparently they can help with the contracts and stuff.
I'll blog when I find out what happens. :-)
