3 Opencart Modules

This project requires 3 Opencart modules. 1. [login to view URL] ARB & eCheck integration into Opencart's payments module 2. Product-Option serial key module 3. Product-Option download module I. [login to view URL] ARB & eCheck integration: We need to allow customers who are shopping with us using our Opencart store to have the option to select a monthly recurring payment plan or to pay in full by eCheck or credit card. These payment options require integration into [login to view URL] payment methods ARB & eCheck. [login to view URL]'s AIM Credit card payment option already exists in Opencart so this requires an integration of only ARB and eCheck. II. Product-Option serial key module: We need the ability to add serial keys to our product-options (i.e. deliver software license keys or training course keys with any product-option or product-option combination). For example if a customer selects training course "A" and we offer instructor options B & C with training course "A" then we need to be able to have course keys delivered for course "A" instructor "B" or or course "A" instructor "C" depending on which course and instructor the customer chooses. The keys should be delivered to the customer through the invoice email and via the order details within their Opencart account. There is already an Opencart serial key module for products but not for product options. The functionality of the existing serial key module is a preferrable model for how the product-option serial key module should function. Serials key should be visible to the customer in both the invoice page and downloads page. You can find more details about the existing module at the following link: [login to view URL] Important note: This module must provide the ability for serial keys to be automatically delivered to the customer depending on the option they select AND allow us to deliver serial keys for product-option combinations they select. ie. ability for use to deliver one unique key for product option combo AB, AC, BA, BC as well as production option A or B or C alone. III. Product Option Download Module: We also need the ability to provide downloads to the customer based on the option they select. The functionality must be similar to the existing download capability in Opencart but instead of downloads being connected to products, have them connected to product-options. Requirements & Other Expectations for this project: - We request experienced Opencart freelancers and examples of previous work with your bid - Delivery time frame 21 days - All modules should be compatible with Opencart 1.4.9.3 and above. - We require modules to be operable in functioning Opencart demonstration sites before paying - No milestone payment - Prefer No file editing & Easy installation - 12 months of support/troubleshooting of your modules * You may re-sell & distribute these modules as your own work after our purchase. Your modules may be re-sold in Opencart extension stores and other avenues so the cost of development can be spread beyond this single request.
