Cost to upholster front and rear seats

Purchased a set of seat covers from Legendary for the front buckets and rear seats in the Duster. Went down to the local upholstery shop to see what the cost to install the covers would be and was totally shocked when the owner quoted $1200 to install the covers, parts extra if needed.

So here's my questions

What should be the cost to install these covers and secondly is there any shops in British Columbia that you folks would recommend.

Thanks
