User wsd is correct, that is not how we would like to offer our domain names. We are offering domain names for x euros with a one time setup fee. The price of the domain name is the same every year, so we do not want to market our domains saying the domain is more expensive the first year, since it's not. Besides, we'd like to give discounts to the setup costs and we also have customers who don't pay the setup costs.
Can we code this ourselves?
