Vue/BootstrapVue expert needed for remotely fixing my application

I need a Vue/BootstrapVue expert for helping me to change/adapt/complete a big self written application. (The backend is done by us. You are only needed for the frontend.) This is a longer/big project but we have to start with a concrete problem: We have an interface where I can upload a file (sending it to a JSON-based API). If that works it asks for a second one, which is uploaded... (And a third). We need to change this into: The first file is uploaded, the system checks if that file is OK and asks for the second one. But instead of sending just the second one, it must send the first AND the second one. (The third upload sends the first, second, and third file.... The files are very small!) OK, it is a little more (there is an optional text dialog) but that is the main problem. (The actual problem is: How do I save the variables between the requests by Vue?) Looks easy for you? I think you will need one or max. two hours for this. The real problem is to understand the existing code and the working situation: Because the code cannot leave the house, we have to use some remote desktop solution (like Teamviewer). So yo need a fast internet connection. I hope ours is fast enough... We work on Linux. Is that a problem for you? Are you able to use vi/emacs or are you a fan of VSCodium? We need the work to be done this weekend! And if we like your work and after you see the complete solution and be interested in more work, you can have (much) more work.... Or if you see what a stupid work that is or you don't like to work remotely with that system, we just stop the work... In the beginning it is only that described problem. After you fix it, we need some days to complete the backend work, and we will come back to you.... Then there are longer work packages! (And also much more complex if you want. Or even design/user interface problems.) The text on the website is german, but that shouldn't be a real problem.
