I arrange cover for a few of the folk on here. I'm sure we can help you out.
If you enter your details on our website www . boothbytaylor.com you can get a rough indication of price. We have insurers that can arrange public liability and professional indemnity into one policy to make a saving. They aren't usually available online though.
If you PM me your number I'll give you call to run through it with you or I'm back in the office Monday. 01245 409506.
