Anyone interested in an e-textbook service?

Personally, I'm tired of not having the option to buy PDF versions of textbooks, or any technical book for that matter. Kindle is awful at digitizing anything other than simple novels and currently most publishers out there don't offer PDF versions of their books. Google Play books are better than kindle, but your book is still tethered to their reader. I'm not sure about Apple books but I'm sure it's the same story. I don't have much time to read novels or fiction, but when I do, I actually don't mind paper in hand, but when it comes to textbooks it's a really painful experience not to have a PDF I can use.

This drove me nuts, so a few years back I invested in learning the best way to digitize books. There are many tradeoffs and learned through trial and error what worked best. I always wondered if I could leverage this knowledge and my equipment to offer a service where you just buy a simple but quality PDF version of a book you want, no strings attached. I'm at the point in life where I have time to do this, but I'm not sure if this proposition interests anyone on IH or anyone for that matter. The process would be simple I think:

1. Request invite.
2. Enter an ISBN.
3. Review.
4. Order.
5. Thumb drive and invoice ships.
6. Delivery arrives.
7. Scan invoice with Papaya.
8. Receipt with repo key are emailed.
9. Decrypt and enjoy!

The review for an ISBN search will provide a best effort quote and estimated ship date. There would be no up front charge for orders, but rather an invoice is shipped and you print and scan the invoice with Papaya. The invoice for an order is only to cover the cost of the textbook and shipping--which you would have to pay anyways on Amazon--but the cost of labor is free. However, for quality and legal reasons, I can only buy textbooks new. Shipments would be discrete, secure, and trackable with sane packaging that fits in your mailbox. I wouldn't offer downloads for many good reasons I won't dive into here, but that fact doesn't really subtract any from what the service adds in value it provides the customer.

The e-textbook shipped would be searchable and overall high quality in terms of color, font, and image fidelity; each book is carefully made over a two day process. The thumb drive would actually contain a git repo, rather than just the book, where the repo contains the invoice along with both the source PDF sheet files and the compiled textbook. There may be a build binary shipped as well, but that's still tentative. In the case I mess up the built PDF and don't catch it, the git repo can be used to pull in the corrected files. So everything ships as an encrypted zipped file, where the key to decrypt it is emailed when your order ships (but the key to decrypt the git repo on the other hand is sent upon receipt).

I don't do this for free however, so no, there is no option to keep the physical book. Overall it's worth a try if anyone here is interested, worst case is that I don't get paid in which case no decrypt key will be sent--but the thumb drive is yours to keep! I'm not interested in trying to scale this service, only refine it, and I would keep it invite only. If you have feedback or questions I would be glad to address them --I'm not even sure people still read textbooks these days, nevertheless pay for them, ha.
