Hank here from Shopify.
The Community Forums are a great place to discover developers to improve or develop stores as well as build almost any custom scenario you may need.
We have a great list of developers for hire known as Shopify Experts, who you can hire to do almost any custom work on your store. If you were to reach out to them about this query, they would be able to resolve this issue for you.
Hopefully, some fellow store owners can offer their feedback on developers that they have used, but the above link is an excellent starting point.
Let me know if you have any further questions!
All the best,
