import/export module for prestashop

Hello everyone, We sell biotechnology products online (protein, antibody, genes, etc) We would like to find a web developer to help us in developing a module to import and export product lists in prestashop. it is an urgent task for us, so we hope it could be finished in 1-2 weeks For import: The module should allow us to import our products according to the different corresponding suppliers in Prestahop, quickly and flexibly. We have about 10 suppliers gathering between 10 around 30 000 products each (total target of 100 000 to 200 000 products. It should include different importation templates (per supplier and sometimes also product type as the corresponding data are provided in different formats all in excel files) based on 2 elements: supplier and product type. STEP 1: Select a template. We would ask to develop 4 or 5 templates at the beginning and more later. STEP 2: Select a supplier. STEP 3: Select a product type. It should also be possible to select “all product types” to make sure we can upload all product types from a single supplier. STEP 4: Select an upload option : - option 1: “update of info” to update all product information and add new products without deleting any product not present in the uploaded document. If the information from a column of the uploaded file are different from the database, the information from the uploaded file should overwrite what is in the database. - option 2: update and delete: it updates information and removes products that have been imported before but do not exist in the new uploaded document anymore. Important: This applies of course only to the selected supplier and product type. STEP 5 Select CSV file and import. For Export: Currently in our prestashop, we have many suppliers and many product types. We would like to have an add-on to help us export the data depending on inquiries. This add-on will enable us to export the products according to the supplier and product type. Process for export: Make a selection in the database by keywords, product type and/or supplier  export in excel file and or specific template that we would develop to be ready to send to customer with logo and nice tables. Please contact us to get a link to the corresponding shop in case you need it and send us your price, timeframe and availability to perform this task. We are looking forward to hearing from all of you ASAP Contact form: Price (€) +expected finished time in days. ex: 200€/ will be finished in 5 days Thank you.
