Just a random thought...
If you (or anyone else reading this) enjoy bargain hunting, garage sales, auctions, etc, you might consider selling stuff on ebay. A number of times I have obtained something for little or nothing and sold it for a whole bunch more on ebay.
The most important point I would suggest is to have a good idea of what you can sell it for before you buy it. I bought a bunch of old books one time thinking I could make some money on them. I didn't know the market for them on ebay. I lost money on that one.
In general I figure if I make at least $10 per sale I am paying for my time to do it; about $10 per hour.
P.S. I went to an auction last night and they sold a real nice stainless steel grill outdoor grill unit for $10, a heavy duty track based snow thrower for twenty dollars, and a lot of other stuff that would have been worth reselling. In fact, I suspect that the guy who bought the grill just left it where it was so he could sell it in next week's auction. If I had thought of it at the time I would have bought it for $12 just to sell it again next week.
If you figure out where to buy things cheap, and sell them higher, AND if you know what you can sell them for when you buy them, there is money to be made on your own time.
P.P.S. Try goodwillonline.com, govdeals.com, policeroom.com and any other online auction site you can find as sources to get things cheap.
