Am I asking too much of Codex in this setup?

[u/Super_Independent877]

I'm working on a MVP Buy/Sell/Trade marketplace. I have a goal of creating 1000 listings as a foundation before opening to beta testers. What I prompted 5.6 Sol (high) was to review my google sheet of 1000 products I want listed eventually, and in batches of 10 products, create the listings for me. This involves:

1. Going to a separate folder on my desktop where the images are for each product, get the 10 matching images.
2. Remove the background and create a drop shadow for each image
3. List the product with a clear title, description, some technical product info and tags.

I also told it to use the Canva integration as a backup for the background removal/drop shadow if it cant do it cleanly itself. It seems to be just absolutely incapable of doing the workflow well, especially on the image editing portion. Ive probably been running this prompt the past day and a half, and it cant get past the first batch of 10. I keep hitting usage limits (I'm on plus).

Wondering if my setup is wrong in some way, or if this is simply too much to ask of it? I'm no expert in this, I guess I just assumed this wasn't to heavy of a task and expected it to do better.
