Independent Contractor

How many of you guys are independent contractors? I have got pretty much everything set up, but I still need to set up my corporation (a bit pricey) and get my insurance. Does anybody know who can help set up a corp for a reasonable amount?
Also, are you guys able to make a fairly consistent living doing this? I'm still working full time as a staff nurse, but I'm gradually trying to set myself up to leave the hospital setting--I can't take much more of "customer satisfaction":hatparty: Thanks for any help
