I set up my own firm first. But for my country (Netherlands) that's really just a simple registration that takes all of ten minutes. Then I sent my resume to a number of agencies that broker between corporations and subcontractors. They usually ask your rate, do the negotiations with you and the end custoner, and take 15-25% margin.

I think it's worth it but YMMV.

Furthermore there's a host of smaller stuff that you need to take care of. Liability ensurance, pension, health insurance, bookkeeping, separate bank account, and sending a time sheet and bill every month.
