You make it sound like a chore, but that is part of the hobby. Indeed, if you are an active buyer of vintage baseball cards, a developed understanding of the market for vintage baseball cards is inevitable. If you are active enough to want to sign up for a yearly membership, you already likely have a pretty good handle on what the vintage baseball card market is. Couple that with a couple of free services like ebay and smartcollector.com, and you will have a hesitancy for people to want to purchase a service they can probably get mostly for free.
I really do not want to discourage the effort, which appears quite impressive. But I would also recommend luring prospective customers with free service, get them used to using it and then start to charge them for the service once they've made it part of their collecting routine.
It is a lot easier to convince someone they need something after they've been using it for free than by charging them $10 for the privilege.
