Then in that case you possibly won't find a planning-type meeting with Business Link that helpful, when dh went to see them he had his business plan all sorted and was quite clued up about his plans, and he said it was a bit of a waste of time. They are really geared up for people who don't know where to start. They might be helpful with premises perhaps, and it's worth asking them about grants etc (eg if you're in an area where encouraging tourism is high on the agenda then there might be something), but you can ask them that on the phone I would think. And their training courses can be quite good as I said.
I did get a good book from them about starting a business that covers all the basics from what sort of company to set up to employment issues, which is a good starting point for most things. You can get it through their website, it's basically a print compilation of all the helpsheets on the web.
