Develop a simple SaaS app with next.js and OpenAI -- 2

I want a simple web app created using next Js. + No vibe coding please + Please bid only if you have experience in developing saas apps in nextjs/vercel + in your bid, please include your sample saas app works + I will reject any bid that has no sample work Functionality of the app is, User can upload an image and image will be sent to openAI with a predefined/hard coded prompt. once the response from openAI arrives, show it on a results page. openAI response will be text only Further, users can signup & signin and they will have simple dashboard app runs on image credit basis. 1 image credit equals to 1 image upload. New users get 1 free credit. paid users can purchase image credits as packages Users can select from 3 different packages essential, standard & extra. in essential package user pays $3 and he will get 3 image credits. in standard package user pays $5 and he will get 8 image credits. in premium package user pays $10 and he will get 20 image credits. so there should be a mechanism to buy packages link stripe as payment processor supabase as database system when image is uploaded and we get successful response from only then deduct the image credit once credits reach 0, users should not be able to upload images until they purchase new credits On front page user will get a field to upload the image, text field to add a name or a lable to the image, and process button. below that you can show the packages and purchasing options. if user selects any package to purchase it should go through a check out process/page to Stripe Dashboard will be a separate page that can be access from front page. In dashboard user can see remaining credits, and past results (as clickable names. once clicked it opens the relevant past result) all the packages (prices,names), openAI prompt etc, I should be able to change in the source code. (I have some knowledge in [login to view URL]) Make this using [login to view URL] which I can host in vercel I will need full source code and source code should be well commented Thank you
