I'm looking to expand my business, however do not want to incur the overhead cost of adding employees but instead hire contractors. There aren't many attorneys in the area I live in and therefore am having difficulty locating legal help to ensure I'm not incorrectly classifying my contractors.

Any suggestions?

This IRS web article is a good place to start.
