Looking for way to make money that work for me

[MaxPowers]

I am 26, and go to college full time. I get paid to go to college, so money is no problem but extra $$ never hurts.
I was looking at ways to make money and wanted to know if anyone can tell me more about surveys and medical studies. What websites are best for these? Get drowned in information when looking here. Some of the posts are so old I worry if they are any good. I want to know one or two of the best sites so I can start and see how I like it.
Is there any site online to get you name out about house sitting besides craigslist?
Has anyone delivered pizza before? I would get a part time job, but I want to set my own hours so most jobs wouldn't work. Someone referred me to look at delivering pizza, saying I can make great money there. Anyone recommend this?
I will also start donating plasma again. The place is less than 2 minutes away.
Anything else? I have nothing to sell, don't want to sell, not good at writing, don't want to talk to people and have no skills.

Max, you're in college, I assume you have some skills

Working from home is an idea. Go to sites like elance.com, guru.com etc. and see what services you'd be able to provide from all that's there. Consider pizza delivery or similar jobs since, while they're not 'cool', they bring in money. What else do you know you can do? Take care of people's gardens? Drive a cab? There's a huge offer of jobs that anyone can do and one might be the answer for you.
