Setting up the .ltd company is definately the way to go, split the shares between yourself and some close(trusted) friends/family members who will let you draw down dividends in their name which will save you a small fortune in taxation.
Whilst setting up a company is just a case of filling in a few forms farming this work out is recommended, most accountants will take on the role of company secretary for around ?250-400 per year.
Company accounts can be produced for around ?500-750 (keep all your invoices and receipts organised to keep the cost down)
If you have any other questions feel free to fire away, i've been involved with a number of company's at boardroom level so might be able to give you some pointers.
