Commission-based sales - p/t work from home

I am looking for an individuals based in the U.S. to perform national telesales and assist me with lead generation. I need people who can commit for at least one month on a part-time basis. I have developed an online service for attorneys (similar to a SaaS). I need someone to cold call law firms across the U.S. to market my services. I can provide you with a list of potential leads but will also expect you to do some work searching for these on your own. The ideal freelancer would have telemarketing, sales, and cold calling experience, as well as exceptional English speaking and writing ability. You will need to know how to bypass law firm reception and speak directly to the owner of the law firm, as this can be extremely difficult to do. Pay will be commission based *only* at $30 per sale and may increase depending on your sales record. You will get paid as soon as I process the payment from your sale, so you may receive daily pay if you're a good seller. However, no sale - no income. I cannot pay you for your calls, so a magicjack or Voip line is recommended. I am looking for someone to start immediately. Again, you must be a U.S. citizen and a native US speaker to bid on this project. Experience with legal sales helpful. Individuals only please.
