I think he gets the work because he does it for cheap, and people love to think that even though it's a cheap price, they're going to get quality work. In his case, it's too good to be true.
You're probably right, Holiday. I used to work at a Tire Kingdom, and people expected the best work, at the cheapest price, and in the fastest time. In reality, at least with auto mechanics, it is not possible to have all three. Logically it is the same in any field. The main reason I went to Poster Conservation was because they had great prices, and assured me it would be a quick turnaround time. Their prices are lower than anywhere else I looked (I didn't look at Posterfix for obvious reasons), the work was excellent, the total turnaround time was about 2 weeks, and they are very nice people to deal with. Doesn't get much better than that, not to sound like an online advertisement, but that was my experience with Poster Conservation.
Great links, Jeff. Based on the videos, it looks like Poster Mountain and J. Fields take a lot of care with their work. Thanks for posting those.
After looking into it, DIY linen backing is probably not practical, but it would be cool if you could prove me wrong, Charlie. I looked into DIY framing a couple years ago, and for the frame moldings I wanted, some good equipment to cut and join the moldings, cut the plexi and foamboard, etc., I would have to frame about 60 one sheets to start saving any money. Since there is a framing place that does my frames perfectly, it really doesn't make any sense to spend that much time, and extra money since I'm not going to have 60 one sheet frames. It's about the same dealio with linen backing. Not to mention the learning curve with anything.
