job platform for hairdressers

I want a compact job platform for hairdressers. The companies should be able to manage their advertisements themselves with login. It should be possible to create, activate and deactivate the advertisements. The store owners pay a graduated annual fee either for one active job advertisement or for 3 job advertisements or for 10 job advertisements. The platform runs only in Switzerland. On the other hand, I would like a sales platform for hairdressing products. So if someone wants to sell his old wash bench. This platform is absolutely free and should serve as a point of attraction to go on the platform even without job offers. The programming language is not important to me. The whole must be however Devicefähig. I pay 2 things. A fixed amount for the programming. And then maybe I give a certain percentage of the income from this platform to the programmer for life. That should serve as a thank you and incentive to program clean and well. I am not a big company. But I have more ideas. And this platform is also a test for even bigger things. There is already an advertising platform for hairdressers in Switzerland. This is an example for me. The programmer may certainly copy functionalities, but there must be no copyright problems, it must be programmed by the user. I myself come from the project environment. I can explain the exact functions without programming anything. I strongly assume that it needs a database. Of course, the platform also has a back office function to manage everything. I am not a fan of having to scroll down long pages. So the functions must be clearly arranged. A good horizontal header in the classic sense fits. The page certainly has pictures. The most important picture is on the landing page, which surely has to be purchased by me. I already have a hosting in Switzerland. You can upload everything to it. Traffic will be available. But not in a way that it needs a huge server. I estimate 200 users maximum at once. Thanks for possible requests. I am glad. I am looking only for experienced programmers from India, Poland, USA etc. Thanks M.M. from Zurich PS: maybe such a platform is already programmed. So much the better.
