Guidance needed before I start

[Xyon]

My site has adverts on it.I wish to use the document general type because there is no add to cart requirement, however I need to refer the buyer to the advertiser. I have the advertiser as the category at the moment. OK so far?
To accomplish the referral process I can think of three possibilities and would like expert opinion before I start.
1.Use a modified 'Tell a friend' which would include website and email links to the seller (category). I need to modify the category to include these details as fields.
2.As above but using the 'Ask a question contribution'
3. Some other easier method that the wiseones - DrByte,Ajeh etc might suggest.

Further to the above - because the seller has bought advertising, their details are available from the account information - so its more a case of referring one customer to another as far as the site goes.

Im not sure I understand what your trying to do?
Why cant you use the banner manager?

Sorry if not clear - I'll try again.I sell advertising space through a normal product general type. People look at the goods for sale and if interested need to contact the seller. I do not get involved in the sale.Therefore I need a facility whereby the buyer can contact the seller through their email address or telephone number. To automate it, ideally they would have a button labelled contact the seller which would bring up contact details and an email facility with the data for the product_id and the sellers email address already loaded.As there is no sale from my point of view I propose to list the products as document general types and modify the product info page to accomplish my needs.
Any better????????
