[Help] Accountancy help.

[Cotton Socks]

I know there are a couple of accountants on here but I can't remember who they are. I'm trying to help out a friend with their tax affairs that are too personal to put on here & quite complicated.
I'm a bit stuck with who they should speak to, to help them out. I don't want tax advice as the damage has been done, I'd just be grateful if someone could pm me & steer me in the right direction as to where they should start.
Just to pre warn, any pm will be met with an essay in return.
