The reliable way to hire a tradesperson

I would like someone to assess and remove a small stud partition wall that forms a cupboard in the alcove next to a chimney breast. I'd of course like confirmation that it's non-load-bearing before any work starts and potentially a quote for boarding over the bare brick wall inside ready for the plasterer once the wall & door are taken out. Does all this fall under one trade and under which category should I post it here? I originally had it under handyman but got no bites.
