Which category of professional should I chose for moving a loft hatch?

Hello, I'd like some quotes for moving (so I guess essentially installing a loft hatch and pull down stairs but I can 't work out the best category to post it in? I've looked through nearly all of then and cant see loft hatch as an option (sorry if I'm being blind or silly!) Loft extension seems a bit of a leap to me and I imagine they'd be looking for much bigger contracts! P.S I've just hit the same problem with posting this question so have opted for builders but am happy to be redirected!
