I'd imagine any upholstery shop can do it for you.
I bought my tear from a fellow in Oregon, one man shop, the mattress he offered was too expensive for me but it was in three pieces.
Laid out it is a queen but lift out two smaller sections, push the larger one to the back wall and drop the smaller ones down to become the backing part and you had what effectively was a bench seat.
I have no idea about the dimensions of each one tho...you could do a card board mock up for l x w and then i'd get some quotes.
I've had some furniture upholstered and there can be quite a difference from shop to shop.
If price is a concern stay away from the design type places that specialize in furniture and try the marine/RV places first, then the auto upholstery ones next.
hope this helps.
