Hi,
First of all the 20 bucks is not exactly what I would call a price ;)...I could imagine somebody getting rather offended.
Anyhow, here are 2 points from my end :
1. you should open this pulse inside Job Offers, and not here.
2. https://addons.prestashop.com/en/data-import-export/47560-orders-csv-excel-export-pro.html - Put some money next to it, and there you have an existing option. It will help the developer and you get a 3 month free support next to it. I wouldn't call that expensive.
I hope I managed to help, and the community is here to help you , usually for free. In case you have a project and some budget make sure you sue the Job Offer section.
Kind Regards,
Leo
