Developer Needed: Magento Product Coding

We need a developer to either edit the code of the default bundled product or develop a new type of product that allows us to deduct inventory from multiple products from a single bundled product. Requirements: Ability to setup a bundled product that will deduct from several products inventories. Frontend will not allow customers to choose number of individual products, only the amount of the entire bundle. Backend will recognize if a product in the bundle is not available and return 'Out of Stock' status. Must work with M2EPro and Embedded ERP.
