It may be time to learn how to do it yourself. Literally all you need is written in the book, "deer skins into buck skins." Start to finish.
Or you could go the slightly quicker crash course by buying a bottle of "deer hunters hide tanning formula." I have found that by salting and fleshing (or just freezing) a hide immediately, and then following the instructions on the bottle exactly when ready to begin working on the hide, that you can make beautiful hair-on garments. I've had excellent results with fox, coon, muskrat, and squirrel.
However, to get the prized leather that is valued for quivers and buckskin garments from a deer hide one will have to follow the method listed in the above book to first make the fur slip, before then continuing with the instructions on the bottle.
There is an equivalent modern method for slipping hair too, and 20 minutes of research will turn up a reliable version. However, the hardwood ash method is just as good.
