Recommendations for side returns

[Choops]

Hello.

We're looking to buy a house and would love an opinion on how much a side return would cost and what is feasible.

Does anybody know of any good, local companies that would come to view the house we like with us and give us a rough quote?

Thank you.

They don't seem terribly reputable, Mumsnet is rife with complaints about this company.
