Retirement exhibitions

I need an email list for sending invitations up to 5,000+ businesses to reserve their place at Retirement exhibitions in both Blackpool and Torquay. So up to 10,000 in total or maximum numbers available within say 10-20 radius of exhibition locations. The strategies can comprise of opt in email lists and social media.

BACKGROUND
The exhibitions are in association with www.thenationalcareline.co.uk which is a not for profit organisation that also offers many free stands to well known charities.This is why costs need to be contained.

www.retirementroadshow.co.uk operate retirement exhibitions regularly throughout the UK and wish to email businesses with a view to inviting them to have a stand. The list will typically comprise of: Solicitors, Accountants, mobility, motability, home adaptations, improvements, maintenance, furnishings, insurance, health, care homes, travel, financial, property, entertainment and activities etc. In fact any product or service that can be relevant for people aged 50+ excluding adult related. The next event is in Blackpool on 18 Oct 2013 and I wonder if a diversified mailing list could be built within a 15 mile radius of the Savoy Hotel Blackpool FY2 9SJ. The next event is in Torquay at the international Riviera Centre TQ2 5LZ on 17 November 2013 and others are planned throughout next year. Shaun
