Create your own  market place where suppliers can list their products and they can then sell through a market place that you manage and control and take a percentage of the sales (fixed and variable costs and charges). 

ALL market place type PACKAGES COME WITH 60 MINUTES OF SUPPORT AND MAINTENANCE PER MONTH FOR UPGRADES AND ISSUE RESOLUTION. Domain registration is extra and costs will be dependent on domain name being available as well as extension (i.e. .co.za or .com etc.).
