For leather work, having a local do the seats and door panel/kicks came out to much less expensive for me.
I traveled to San Diego, due to local prices (locals wanted $5-6K), to have mine done. Plus I wanted mine done to my design spec's.
Cost was much less than Gahh or World upholstery. The $3k for just the seats was more than I paid for my entire interior. And you will still have to pay someone to install them, and do the door panels, and kicks.
I personally don't think that Gahh or WU is the way to go.
Can't remark as to quality.
Psychrunner, don't know where you are located from lacking info on your sign in.
Seams perfect carpet sets are reasonable cost and done well. Mine were not long in coming as previously reported.
