Updating Site Links, Meta Descriptions and focus phrase for web sites

I have two content web sites. One of them is selling electric scooters and another one is selling electric hoverboards. I need someone to go through every page of the web site and update the amazon links of products that are sold out or no longer available. I need you to then go on Amazon and find the closest product and update the links on the site.

Then, for the articles where there is copy for that specific product that is no longer being sold on Amazon, I need you to create a document that has a link to the Upgrade to see actual info this document you will also need to identify all of the content in the article that needs to be updated (I will contract with someone separately to update that content).

The sites have approximately 200 total pages between the two of them. I would say that only 30-50 articles need to be updated. I think this job could be completed in 25 hours.

I also need this person to go into all of the articles on the site that don't have meta descriptions and "focus" phrases assigned and have them write those. On one site, almost all articles have this information. On the other site, there are probably 75 articles that don't have them. Time to complete this would be approximately 4 hours.
