CRE B2B modifications

I want to create “my version” of ecommerce cart. The system will be based on CRE B2B. My main site for selling the cart should use the “my version” cart. Main site need to have a reseller system (see below). The carts (a few levels, based on features) will be offered as a hosted solution, example: the end user chooses a package, enter relevant info (domain name, billing etc.) and within min. he will get emails with the welcome/ login info to his new hosting and ecommerce cart. All modifications below need to be created as option modules to the cart, none of the existing modules should be deleted. 1. To simplify the FDMS process* 2. To have the ability to allow to buy as a guest for the whole catalog or only for selected product 3. To add the option of one page checkout 4. To add CRE Content Director* 5. Add an info box “subscribe to our newsletter” (with the ability to unsubscribe) need to be able to add promotional text to the info box from admin, example: subscribe to get updated on the latest….* 6. To have the ability (an option) to open the product description page as a pop up 7. Poll system* 8. Forum* 9. Live help* 10. Ticket system* 11. Auction system* 12.

CRE SEO URLs* 19. add EPay Enterprise payment module 20. make sure customer can upload an image to the cart from admin (I think right now its only with ftp) Modify the template system- (link in site owner admin to c/panel hosting.) 1. add the ability to edit the header, footer and contact us page from admin 2. brand the front-end (catalog) and backend(admin) 3. news feed to all admins 4. add a selection of basic templates (please quote per template) Data feed – 1. CRE Loaded All-in-One Product Feeds* 2. Data feed to Accounting software: quick books*, Microsoft money, turbo cash*. 3. automatic data feed from any “my version” cart to the other (store owners can sell each others products) 4. data feed to EPay Enterprise shop Reseller system (AKA: mall, drop-shipping, white label reseller, franchise)* -Front end (catalog) should have a reseller section, end user can go and open a store in minutes -I want to be able to control the number of resellers I allow for each package (cart level) Example: basic – can have 10 resellers, pro- can have 100 resellers, mega - have unlimited resellers Features: Store owner admin- 1. Ability to set up different product price groups for different reseller level 2. control what products each reseller level can see 3. ability to give the reseller site for free or to charge for it (recurring or one time) (can charge different pricing for different packages) 4. full admin control over reseller Reseller admin- 1. markup prices ( type amount or enter %, product by product or for all list) note: prices can not be below the reseller prices 2. Edit header, footer, contact us. choose from one of the basic template or upgrade 3. News feed section (so I can send them news of updates etc.) 4. Customers report, profit margins reports etc. 5. What other modules from the main site we can give to the reseller? All suggestion, comments, questions or ways to improve the above will be gladly welcome * Existing modules in the market that I know of, some will need to be upgraded and modified Q. is there a way to make the B2B system faster and lighter?
