TeleMarketeer Needed, Urgent Start

I'm looking for an experienced driven telemarketing professional to help penetrate a number of vertical markets where we currently have a reasonable market presence but need more. Experience of catering would be a useful value add but B2B sales is an essential prerequisite. We have some data to work from but would also need the post holder to warm, quantify and clarify some raw data into something more useful.
Looking at 20 hrs per week for a 10 day minimum campaign based in our offices in SE1
