I've posted this before but I've made half decent money in small batches by purchasing crates of assorted goods at live auctions. Police auctions are sometimes good for this, as they may just load a heap of stuff onto a pallet and sell the pallet as a lot. Most people don't want to buy a pallet full of junk, but you can get lucky if you scope it out before the auction and look for valuable items. Same goes for office liquidations - you might get a bulk lot of 10 LCD monitors or laser printers or something like that. You can sell the first 1 or 2 on eBay, get your capital back and the rest is pure profit. It's also easy if you buy a bulk lot because you only need to write the listing once and just keep repeating it, plus you can get a feel for what days/times bring the most bids.
It's not terribly scalable because you need to have transport and time to attend auctions, plus somewhere to store the stuff. But if you have a decent sized car/pickup, proximity to auctions and a nose for a bargain, you can pick up some good pocket money with this strategy.
Incidentally, I think the market for the pricenomics data is precisely the same as the KBB market - detailed lookup via mobile app for people who are buying/selling regularly. A good pawnbroker/2nd hand dealer/auctioneer will know the price point on a wide range of goods, but allowing people to purchase this information for a reasonable price will help both people starting out, and also professionals stepping outside their bread and butter.
I would suggest a freemium model, where the free version gives you a price range, and the pro version gives you a very direct price.
