I currently have a webstore active but believe wordpress may be more capable a system for achieving my goals. The inventory is largely multimedia - books, CDs, Vinyls and hopefully soon ebooks.
The site would need to have a fully functioning cart system as well as Bitcoin integration - this can be achieved through freely available plugins for wordpress of which I would send you once chosen for the project.
The site also needs to be able to support a very extensive inventory, currently at around 300k but I would be looking to expand that extremely rapidly in the near future so it is imperative that this can be supported.
I populate my webstore and marketplace venues with my inventory using a third party service which again would need to be integrated into this process. I upload my inventory files to them and they send them on to the venues. Details of what this service would need is here: http://wiki.theartofbooks.com/index.php/Custom_Venues
If it is possible to populate directly and effectively directly to the wordpress store I would be open to exploring that feature.
Webhosting and other general fees associated with the set up would be covered by myself but quotes will be needed first so I can be sure all the options are sensible.
