Small niche exhibition wants more visitors

We're a trade exhibition with loyal customers and run an annual trade exhibition. It's a one day event and we want to relocate to the Midlands next year to match our clientele. We've a five year track record elsewhere but need to boost numbers. Our target audience is old school and social media won't cut it without postcards too. The ideal person is savvy online and knows small exhibitions. They can call potentials and work a location through sheer doggedness on the phone and a bright manner. Raising awareness and converting visitor numbers is the job. Well do the selling and you'll have a solid brief. It's no hard sell and our customers are our friends. You'll be adding to our database all the time and involved in supporting the core team with solid proposals. Ideally we'd have a fixed fee over a set period. You would be judged on increasing the numbers and our database data.
