It would be great if you can pull this off and get a complete strut assembly for about $500 per corner. A few folks have tried (search this site) working with some of the more popular low priced shock companies but the initial order quantity was the big barrier. What I make and sell is done to order and I sell about 6 kits a year.
At the $2,000 price point you'll probably sell 10 to 12 per year. The biggest issue for the manufacturer will be cores. A complete set of used struts runs about $250 and then there's the labor involved in dis-assembly, cleaning, inspection, shortening, and assembly.
