B2B Events Sponsorship Sales

I am in need of a freelance B2B Events Sponsorship Sales for a niche event we are planning in a few months time. You need to be very comfortable with sponsorship sales, follow ups, lead generation, cold calls and face to face meetings, if needed.

Someone based in or closer to London will be preferable, in case of scheduled client meetings etc. My budget is £10-£15 / hr and can be up to 20 hrs per month initially to get a feel of how you work.
