Bubble.io App Developer

I have an app that is a Ai ad scriptwriting tool. It is already built, but I need some upgrades and changes to it.
It is called AdScripts. It allows users to fill out some information about their product or service and their ideal customer, then they can generate a video ad script in seconds. Once they will out the info about their customer and their offer, they can generate as many scripts as they want.
They can also store their scripts in the documents section of the app.
They can also chat with the scripts they generate to fine tune them.
This data is sent to OpenAI through an API, and then it generates an ad script based on specific frameworks that I have setup in the prompts.
I have various changes that I need down to the app like:
Allowing users to create their own ad templates by giving it their own prompts.
Adding folders to the documents section.
Add a word count calculator to the documents section.
Video transcribing into text. Just upload a video or audio file and have it transcribe it.
I have a list of changes I need done.
Please provide links to any apps you have developed with Bubble and your rate.
Please respond with any questions.
Thank you!
