Hey there,
I understand that you take XML from 1 website but the sizes are for retail, but you're selling wholesale. So, yes, I am delighted to inform you that I can change this and make it according to your requirements. I have multiple years of experience with these kinds of tasks.
I have excellent work history, top ratings & feedback from my clients, so I assure you that you're in the right hands. If you have any questions or concerns, please let me know at earliest.
Best Regards,
Wasif
