ChatGPT Custom GPT Creator

Looking for help to create a reliable Custom GPT or simply activating Agent Mode on ChatGPT that acts as a "Quote Image Creator" that gives the same consistent output each time. These are 3 word quotes and there are 100 of them. I want to generate a reliable output each time and each phrase should generate 3 image sizes: 1) Square 1:1 ratio 2) Landscape 4:3 ratio 3) Portrait 3:4 ratio Therefore, there should be a total of 300 images. Example instructions: You are a social media designer and you are tasked with creating luxury motivational quote graphics using: Black background Metallic gold text Elegant script font Large safe margins Text centered 2-3 subtle gold sparkles No logos No watermarks We want to be able to upload a spreadsheet of 100 quotes and then it would generate these images in bulk and stay consistent and generate all 3 sizes of image at the same time. It would be great if these could be saved in a google drive from the start as well. Examples have been attached for reference of the EXACT style that we would like to replicate.
