Magento modification to Xtento Stock Import / Tracking number export

I require a Magento developer to work remotely. Here is a list of modifications required Functional Modifications: 1. Stock Import Module by Xtento We would like all associated products to update stock quantity to show the quantity of the configurable product. For example sku 848 is a configurable product and the associated products sku's are 848_1, 848_2. 848_3 etc. So if stock for the configurable product changes the associated products are also updated. We have setup configurable products as the sku to be imported. Our associated products are named with an _$number. Create a multi array of configurable products and their associated products When importing check if configurable product isset and either update stock or insert associated products into the xml file before importing 2. Tracking number import by Xtento We would like the tracking number module modified to update the sku with the correct associated product sku then either insert into xml file before importing or update the order tracking number directly. However we would still like the functionality to be able to update partial shipments.
