I would go further than Bob - in my opinion, 10,000 images will drive you mad, will take a long time, and I think you might find yourself resenting the process instead of enjoying the gems that you find.
I recently had a similar dilemma, and I ended up giving my family archive (around 2,500 negatives and slides in rolls and strips) to a specialist shop to scan on their Frontier. It didn’t take long, was painless and I enjoyed looking at the images.
The fun then is to pick the ones you want to scan at high quality on your own machine which is what I’m doing now. Hopefully, there is someone in Denmark who’ll be able to do this (I don’t mean a drugstore!!) or if you’re willing to go international, I can suggest where to get this done in the UK.
