Customize pricing for a plug installed and syncing products

Seeking an expert to work for a few hours on our project. The project entails customizing the rate quote engine from the plug in we purchased to our pricing calculations. Equally, the second phase of this project is to sync products via api or ftp upload from woocommerce to the plug versus us individually uploading per product. Bottom line, making our commerce store auto work with the plug in and quote rates in our method since plug is missing some parameters. Only accepting someone ethical and honest. Time of essence value. Developer needs to convert project back to us quickly.
