Should i do commissions~?

what do you guys think. would you buy them. whats a good price. i have never done them before, but i mean, i think i've reached a higher quality of art then i ever have before, and i think its enough that i feel i could create things for other people and charge a little for it. 

real cash with like a paypal would be SO FRICKIN COOL...is that complicated? you guys who do that? is it hard to set up/do transactions? should i just sick to points? 

thanks so much for all your input/advice, guys!
