Yes, there are people you can pay to do this. There's also free help available for writing plans. If you're in the UK, Business Link helps with the format of the plan.

If you're not applying for funding, your plan doesn't have to be overly complicated. It needs to set out how you've reached where you are, what you're planning to do, who you'll do it for, how you'll do it, how you'll find your customers, what you'll charge them and how many of them you think they'll be and whether there will be lots of repeat business or if you'll need to keep finding new customers.

Provided the costs of doing what you're going to do are exceeded by the sales you expect, you probably have a viable business. You also need to take into account who your competitors are, how they do what they do, what they charge for it and what makes you different from them.

Good luck!
