Simple price updater for Prestashop & cron optimisation

Hi there I am looking for dev who can make for me a simple module for PS 1.7 It should work: > Download the file from the wholesaler in *.xlsx format - A sample file is attached > Update prices and quantities according to the product codes - all codes have a digital format XXX-XXX eg 620- 015 > If the PS database contains a code in the format XXX-XXX that is not in the file, set the available quantity to 0. > I would like it to run via cron I also would like you to take a look at my current cron jobs to optimise them. I would like to establish permanent cooperation for further modifications - if necessary - and other work on the shop
