Looking for an Angular developer

Hello, I would now briefly describe what I imagine and if you understand it, it would be great if you could give me an approximate price because I have a lot of offers at the moment and am comparing. Following app: There should be a Qr code scanner on the homepage with which one can read in a code and thereby get a collection of z.b products. The products each have a detailed view. You should be able to save the collection with the appropriate title and also delete it. For that, I would also need a small backend where I can enter the data with the Qr codes. You can imagine it this way: you are in a museum. You are forced to go there to download the exhibitions via QR code. You can also save them and view them later and delete them again. It should be possible to store several exhibitions of different museums. I do not need a great design. I just need the functions so that I can continue with the source code. Design would come later. I hope I have been able to explain that well so you have an idea how it will look priced. greeting
