I require a letter offering Advertiment Opporunites

I run a website, and is currently Ranked with Google on page 1. Its a website aimed at students, their Families and Universities. I am adding an addition to the website, A Business Directory for Local Buisness to advertise their Business within my website at very competative prices. The local Businesses that I am looking to target will all be relavant to Students, University and Their Parentrs, ie, Letting Agencies, Driving Schools, Florists, Bars/Resturaunts - Etc. I feel that this is an excellent opportunity for Local Businesses as their Business would be held on part of a page 1 ranking website and will be able to viewed by over a million students throughout the UK.
