Sofa Upholstering And Make Washable Cover (Where? In Bangkok)

Hi do you know anyone who can upholster a sofa which look like this:

2 + 1 seater (cheap leather). no part (back rest or seating) of it can be removed .. except 2 seater and 1 long seater are stand alone.

It is currently torn in several places in the seating area (like a blade cut).

What is the typical cost to upholster the sofa? time? need to take back to workshop..?

What is the typical cost to make a cloth (washable) cover which can be put on top of the sofa? time? need to take back to workshop?

Where can i do this.. (Bangkok Rama 3 Area) please advise asap.. thanks.
