Small WooCommerce site needs help to make Google listings and ads compliant

I have a small website with about 60 main products which we would like to list properly on Google shopping and advertising. Our current Google free listings and paid listings are disapproved for reasons that we cannot really identify and this is why we are needing a specialist who can sort this out. I need a specialist who can go on to our website and make the listings comply with Google requirements and then go to the Google merchant centre and validate our products so they get listed higher in Google search. Thank you Michael
