Limited?

[bodleeds]

Hello.
I need some advice please. I am a sole trader for 20 years. I find that the company is big enough to stand on its own and wish to form a PLC. I have no idea on how to go about this {thick as a short plank}
We started our new years trading on April 1st this year. I really need to know what I have to do. What type of accountant I need. What to do about VAT as I already pay as a ST. Can I register in one name and trade as my current business name? What shares and their value do I have to issue? basically everything I need to know about how to go from ST to PLC. can I use the first quaters figures in the new LTD company etc etc etc.

Many thanks
