Definately get a business phone. See if you can get a number that is easy to remember, something with as many 0's as you can get. My numbers are 296-1000 and 293-7100. Much easier to remember. I had a cell phone that i used as a business phone that i put on all my ads, biz cards etc. I cancelled that and got business lines installed in my office instead. With a business line your automatically put into the yellow pages, its a more familiar number to the public, and it looks more professional. You can always have it forwarded to a cell phone however.
