I've set up my company (Stochastic Technologies) using one of these services and I can attest to it. I paid about 15 GBP, not 3, but it was ready in half an hour. The HMRC (the equivalent of the IRS) people are as polite and accommodating as people who take your money should be, and everything was very straightforward to do.
Can I just ask something on an unrelated note, since you've been down this road: what are the costs of a Limited Company, in the long run? I've read that when tax time arrives, it's nearly impossible for a non-accountant to do, and so it'll cost a minimum of £400 for even the smallest company. Not a crazy amount, of course, but it'd put a dent in the profits of a young startup or side project. What's your experience been like?
That is accurate, I had accountants quote me £1,000 or more for ten invoices a year. It's absolutely crazy for something that takes two hours a year to do, and it seems to me like the space is ripe for disruption.
Fortunately, I found a much, much cheaper accountant. I don't know if it'll come back to bite me in the long run, but it was the only way to keep the company profitable.
