Judging by the photos, it won't be done by September regardless of who does it. Tyler would be a good choice if you do fire them. Looks like Los Wages to my TeeToe.
The finish work is everything on a car. If you have the skills and knowledge to do it yourself. Nobody knows your taste like you do. If you are an anal fuc. like me, maybe your better off with someone else doing it. Be done alot sooner.
