From the description it sounds more like you are contracting, not freelancing?

A contractor is typically on site, or sells his time (and presence), meaning he has one client at a time.

A freelancer to me works on projects, and will take on multiple clients at the same time.

A freelancer is usually an independent contractor, so they're a subset of contractors.

You get a certain kind of freedom with freelancing but it does get tiring to chase people down for your money.
