Advertising sales on sportscars website

Our sportscars website has approx 200,000 hits per month from mainly USA Canada and Europe with no promotion or advertising to date. The site is easily googled and many visitors staying on the site for many minutes. It is our intention to sell advertising space on the site and therefore have decided to throw this opportunity open. The advertising does not necessarily need to be car related but obviously the name of the site would bring interest in this area. We have recently launched an app appropriate to the site content. We look forward to receiving your proposal
