Programmer OpenCart

For the online womens clothing store on ocStore 3.0.2.0 looking for a programmer to perform the modifications.

Tasks:
1) Installed the module "Automatic processing of price-lists" for parsing goods from the suppliers website. Previously configured the loading of the goods on the price yml, available here. Is not working to upload products (only update of prices and stock). You need to understand why stopped working to upload products and fix the problem.
Links can provide. This is the most important and urgent task.
2) Replacement system filtration products module OCFilter.
You will need to style the filter OCFilter under their current view on the website (use the filters: price, size, color, season).

Please, write your price for each task (min and max) or the hourly cost and time. Access can provide.
Thank you.
