I'm in the process of trying to sell ad space on my site(s) for the first time to real advertisers who have contacted me.
Right now we've negotiated a price via email and the rep is asking that I send him an IO (insertion order) and an invoice - apparently it goes to a separate advertising department so he hasn't supplied me with banners, URLs, # impressions they want to buy yet, etc.
What exactly do I need to do? Judging by the one I found on MyComputer.com an insertion order is a contract between the advertiser and site - but I don't have a fax machine or a contract written up. Do I really need all this?
For the invoice - What do I put in an invoice if I don't know what they want to buy yet? I only know they are interested in an exclusive top position banner ad campaign on my site.
Any help would be appreciated..
