Rob,
Theres definately a market out there. If you want to use our products we can get them to you by monday morning. Just call us tomorrow.
I'd just like to mention something. Leather is the most easiest thing to clean. If you just want to clean it then don't be scared. Ask anyone who cleans leather...........its so straight forward and simple.
You just wipe your cleaner on, apply a protector and you're done. All I say is to do a pre test before doing the job. As a rule of thumb, without training, just drop a drop of leather cleaner on the leather, if its absorbed its going to be difficult to clean, if it is retained on the surface, it will be dead easy. No training is really that necessary if you just want to clean leather.
Training is necessary if you want to be able to clean and/or repair the leather that may turn up some problems. But you pre tests will tell you if its goind to be problamatic.
