Ok so I know about clinical research, telecommuting, surveys, selling on ebay, mystery shopping and merchendising. What else is out there to earn some extra cash?
Well, you could become a Straight Dope Message Board Administrator. Those guys are raking in the dough.
Yep! I yearn to be an Administrator, cause I hear they make over twice what we do. 
I think this thread needs to stretch its legs over at MPSIMS. You’ll get more answers and there really isn’t a factual single answer.

Most of us (not all) eventually give it uo and get a job.
I know, boring.
Prostitution’s legal in parts of Nevada, but I knew one (ex-pro) and she said it’s not all that great. Boribg, actually. 
How about some particulars?
Peace,

why was it removed from the questions thread?

From samclem, two posts above yours:
General Questions is for questions with factual answers. Your particular question lacks a factual answer, so it was moved. (Although I’d go so far as to say you’re really looking for opinions, but I wouldn’t want to step on a mod’s toes…)
What about lawn-mowing, or dog-walking? “Odd jobs” can be fairly rewarding during the summer months. Take an ad out in your local paper that lists all the things you’re willing to do. Set reasonable fees, and your almost sure to get a few hits.
Good luck.
Read what samclem wrote above. GQ is only for a single question that can be addressed with a factual answer.
You’re asking for advice.
Some posters are giving you shit 'cause you’re a newby, and your query is (to others) mundane. Not your situation, but the question itself.
It’s not likeky someone’s going to tell you about an easy, no hassle, no work way to earn some cash.
Are you looking for a job?
If you knocked on my door and said “I’ll mow your lawn right now with your mower and gas for $25” you’d be hired on the spot (well, except its raining). If you did a good job and you asked if you could come back in a week, I’d wait for you.
How about the kind of part-time jobs that are well-paid for the time you spend on them? Newspaper delivery is supposed to pay well for a couple hours a day if you don’t mind getting up before the chickens and have your own car. Pet sitting is pretty good, too, for the time it takes to do it.
I haul furniture on the side. I put up flyers in my apartment complex to advertis my services. I don’t get enough responses to quit my day job, but some months it really adds up.
You kinda have to have a pickup truck or minivan for this, though.
Maybe you could be a freelance “rent-a-geek” or a general contractor?
Taxi Driver, Pizza Delivery, the Phone missions, Ambulence missions, getting money from your properties once you complete all their missions (the car dealership gives $9000 a day once you collect all 4 sets of cars!), killing pedestrians and taking their money, the list goes on and on.
If you have a truck, you can help people clean out their garages and haul off the junk. Then you can sell it on Ebay.
Is Ebay the modern day garage sale, flea market, or what? I know it’s gravy for FedEx, et al.
So, J0BLESS, you gonna subscribe (to the SDMB) after you start pulling in all that cash?
If you live in one of the cities craigslist.org serves, you can find folks who are wanting odd jobs done. There’s often folks offering lawn mowing, painting, errand runner, pet sitter gigs that may last a day or two or even longer. There are lots of smaller businesses that advertise there, as well as market research, focus groups and medical studies. I check it out every day now.
