Issues with Facebook shop datafeed

I've got a Facebook page and shop that is showing errors.

These errors from the Meta report are:
A Category-Related Field Is Missing
Information in these fields should be 65 characters or less
Universal IDs Are Missing
These fields have missing information
Value must be positive

There are 75 errors in all.

I'd like someone to rectify these errors and also make sure that my shop is set-up correctly.

I'm looking for quotes for this project.
