It is a modification work as it depicts and it must work for you better than ever. I am free to perform any operation to make it feel best.
Some quick question:
1. Exactly how many product do we need to perform operation on?
2. We might need CRON JOB SCHEDULING to, not to get your current work disturbed, are you ok with it?
I am Good in English:
1. I can firmly update the content and provide them ease-of-use.
2. I can make pages look decent and have no problem in editing DataFeeds, if needed.
3. I need the URL of you store to analyse the Pages, Product, Category, Listings and associated data.
Should you be comfortable to discuss in-depth about the product, we can share our contact/s. I have my associate based in States also (Just in case you want to meet them or talk to them).
Hope to hearing soon!
Have a nice day!!
