I second what Flash says. If you read any comments on this forum about them, the common theme is they are slow to pay. A job I did on Dec 1 was paid on Feb 21. Their editors, however, sometimes leave comments that make you shake your head. I have never had an issue with them paying me.
The editors can be a little picky, but otherwise a great company.
And I love the variety - For them I've done movie theaters, package mailings, restaurants, conv. stores, retail stores, and most recently just some pictures of a closed sub shop.
