A ready-made bulletin board solution is required

I am looking for a specialist with a ready-made solution for a bulletin board site that can be quickly adapted and launched. Basic requirements:

- Platform: WordPress preference with a ready-made template and settings. I will also consider solutions based on popular PHP frameworks or Django.
- Design: simple and unobtrusive, Avito-like, easy to navigate.
- Categories: standard sections for bulletin boards - buying/selling things, cars, real estate and, possibly, a separate account for craftsmen and companies providing services.
- Monetization: In the future, you will need to be able to sell advanced features. It is important to have or be able to integrate with the Stripe payment system.

Please provide examples or links to demos of your similar projects so that I can evaluate the solution. It will be a plus if the performer can help with SEO.

Include deadlines, budgets, and examples of work.
