Submitting own small company accounts?

I run a limited company which is just ticking over. My accounts for the year ending Feb 09 are almost identical to those of Feb 08 and I have very accurate P&L and Balance sheet.

I've always used accountants for Corp tax calcs and accounts submission but I'm finding it hard to justify the 700+ I expect to pay. I also have the full CT calcs.

Is there a recommended good guide to d-i-y submissions handy on the net?

Thanks
