Google Merchant Center Optimization / Reviews.IO Expert / Shopify Optimization Needed

I’m looking an expert to come in and optimize my Google Merchant Center feed for better organic visibility as well as fix several things inside the account. You need to know MC and Shopify inside and out and have lots of experience with both. I need someone that can do an audit and tell me what needs to be done, then execute all the changes needed. Here is what we need fixed: 1. (and most critical) Need our Reviews.IO reviews to be imported. We just setup this new reviews platform in Shopify and need it to pass product and store reviews through to merchant center. There could be updates needed to product mpn's for it to work properly. There have been many manual updates made in MC so our Google/youtube Shopify app now shows something completely for over half the fields, including images that don't update when we add new ones to Shopify. Is it best to have all of our changes (including these) to be updated in the Shopify Google/Youtube app? Need you to execute if so. I feel like our product category might not be correct on some of our products. There isn’t a direct clear cut category, but want whatever our competitors are using that are showing up better. Thinking this might help our ranking. Want our listings completely optimized to show up better organically. The goal is to sell more products by getting better organic exposure. We also run shopping ads. We need more robust descriptions, other fields that should be filled out that aren’t, etc. I want you to do an audit and tell me everything that needs to be done, then most likely want you to execute the changes. I can provide product overview, competitive advantage, details, etc, and if you want to use AI to write, that would be OK. We have just started a robust supplemental feed with product highlights, descriptions, etc, but would like you input if we are on the right track. Bonus but not necessary for this project. We would like to test out adding AI images of our products. This will most likely have to be AI mixed with an artist rendering to get the structure close enough. Will also want Microsoft Shopping to reflect changes/optimizations. I believe there’s around 70 products with 5-6 variants each. Please include examples of other successes you have had in optimizing other MC feeds. I would like you to keep a spreadsheet log of hours worked on the project if Upwork doesn’t already do that. I will setup a gmail account for you to log into accounts. This will be a white label setup.
