x-cart functionality modifications

Hi, i was looking for someone who can make a shipping mod that would fulfill these requirements as i'm using the virtual mall feature with vendors from different parts of the world utilizing their local shippers. If you also have any suggestions on how to solve this problem with an existing mod that would be welcome as well. 1. Project aim Provide customer the different shipping methods for providers/vendors 2. Software version x-cart PRO 4.1.9 [login to view URL] 3. Features' descriptions Note: vendor = provider 1. Now each provider able to define shipping methods for his products using standard page [login to view URL] This functionality will stay unchanged. 2. In the customer front-end shipping cost will be calculated as sum of shipping cost of each provider basing on the provider address. 3. When a customer adds the products to the cart from the different providers and submits the order, the order will be divided into several sub-orders (separate orders) by providers as it is now. The cart view will be the following: ------------------------------------------------------------ Products selected are being shipped from multiple locations. Please choose appropriate shipping method for the products. Products for provider1 productid 1 $10.00 productid 2 $10.00 provider1 shipping address <shipping dropdown for provider1> Products for provider2 productid 3 $10.00 productid 4 $10.00 provider2 shipping address <shipping dropdown for provider2> Subtotal: $40.00 Total Shipping: $10 Customer pays: $40.00 -------------------------------------------------------------- I.e. the separate shipping methods selectbox will be displayed for each provider so customers can select different shipping method for each one. If there is no available shipping method for some provider, the error message being displayed instead of the shipping selector and the checkout will be unavailable. 4. Then the order is placing, it will be split by sub-orders for each provider as it is now. Suborders will be regular orders. 5. Admin and customer will receive order notifications for all suborders (one separate e-mail notification for every suborder). 6. Order notification for provider will include products of the certain provider only. E-mail templates for provider and customer will be the same as it is now. 7. All other checkout features (such as 'Google Checkout') will not be changed in the bounds of this modification. 8. This modification will work with USPS real-time shipping carrier and also with user-defined flat shipping rates. I'm looking also for another mod to allow all the providers to be able to process their own orders. I would also like to integrate these ready mods into the site that: [login to view URL] [login to view URL] [login to view URL];page=5 (osticket, or troubleticketexpress) [login to view URL];page=2 [login to view URL] [login to view URL] [login to view URL] (either one of the above minicarts, but needs to be able to work with the shipping mod i'm asking for above) [login to view URL] Any of these mods need to be available to the individual providers to use, such as the packing slip, or the orders management etc. If anyone is interested please get in touch with me or send a quote. You can view my current cart at [login to view URL] for implementation purposes. I'm not exactly sure of which mods above will work with my cart, but please let me know in the quote, or when you contact me. Thank you.
