I need a telecaller

I'm looking to recruit a freelancer who can help me actively seek new clients for my website and follow up on some of our leads.

I'm getting lots and lots of linked-in messages from some interesting companies and I need someone to follow them up and introduce our business and try to get them to list their machines on my website.

I would need someone proactive. I can get the leads but I need someone to chase them up.

Must be fluent in English to approach the companies. Would prefer a female freelancer who has good telephone manners.
