Make money hunting for and selling crystals

What do you think about crystals?  For thousands of years, there have been people who have ascribed all kinds of powers to crystals.  While the healing, calming, or spiritual effects of crystals can be argued forever, they are really cool looking and interesting rocks, either way.  Lots of people like them, some people swear by them, and there's a market for them, which means there are people who make money for finding crystals of all sizes and kinds.  

I live in the San Fernando Valley these days, just north of Los Angeles.  I know of three New Age stores that sell crystals, lots of crystals, within a couple miles of where I'm sitting right now.  If crystals are of interest to you, this is another world where there are several ways to make money.  You can go out, stake a claim, and dig up and collect the crystals, or you could buy them wholesale and sell them to retail crystal buyers online, or in a brick and mortar store. If this idea appeals you, check out these videos as a starter, and do the research to find a niche in the market that works for you.

Make money pressure washing trash cans

Here's a quick video about pressure washing big, plastic trash cans for people, as a side gig or small business.

This is a side gig/small business idea that I learned of recently.  A video I saw about trash can cleaning said people were charging $35 to $65 per trash can to do this.  In upscale areas, like many parts of Southern California, where I live, that seems possible.  In more working class areas, like in this video, more normal, mainstream America, he's talking about $12 a can.  

This is a side gig where you can start small, with one of the cheaper pressure washers, and test the market, before spending more money to build up the business.  If this is interesting to you, do your research, talk to some neighbors, see what they think, and price some pressure washers, if you don't have one. 

Another part of this business is that, if you have a higher quality pressure washer, you can upsell people and pressure wash driveways, patios, decks, and other things.  

Make money getting golf balls out out of gold course water hazards

I heard about this years ago, and just looked it up again to see if people were still doing it.  You can get lost golf balls out of golf course water traps, and sell them.  I wouldn't recommend this if you live in alligator country here in the U.S., or at the Carbrook Golf Club near Brisbane, Australia (just watch the video).

I ran across this idea several years ago, when I was back east, and couldn't find any job.  While it wasn't for me, it stuck in my mind.  This can work a couple of ways.  Either you make a deal with the golf course owner/manager, to either scuba dive, or drag/rake the bottom of the water trap ponds, to recover lost golf balls.  You can provide the service for free, and then wash and sort the balls, and sell them on eBay.  Or you can do this for a fee paid by the golf course, and give them the balls to resell.  Do the needed research, and talk to golf course managers, if this sounds interesting, and see which method might work for you.  

Here's a news segment about a golf ball retrieval business in Virginia.  There are 3 or 4 kinds of  "rakes" to do this from land, from this to this.  So scuba diving to pick up the balls is not the only method, though it appears the best method, if you're a qualified diver.   Then you can make deal with the golf course, and sell the balls back to local golfers, or on eBay, Craigslist or similar sites.
