hi,
If you have all the information in csv or excel, and you have the domain installed with magento / m2e and I can install the prodcuts to your website. I can show you a demo as well for an hourly rate on Teamviewer if you like to so that you become more profecient in managing the products,
Do send the csv and I can check for errors before uploading to magento,
best regards,
TGS
