ANDROID L2TP VPN CLIENT APP

Please read carefully before contacting me, thanks. I'm a C# developer and I'm working on Android Application, I need someone design a Xamarin Form with below controls: 1. A Dropdown list box to allow user choose a server (call a web service to retrieve server addresses and populate in the dropdown list) 2. Free textbox to allow user enter the vpn username 3. Free textbox to allow user enter vpn password 4. Connect button The connect button should create or edit a L2TP VPN profile and then it uses the VPN profile to connect Android device to VPN, after connecting it should show an image on the form then it will show disconnect as well button and it will disappear connect button and textboxes 5. Disconnect button can detect the VPN profile and disconnect it, 6. A background worker should check VPN profile and if it was disconnected accidentally then it should connect it again without notifying the user 7. When app opens it should check VPN connectivity and if it was connected then it should show disconnect button and disappear connect button and textboxes I will do other thing by myself and I need someone create this form for me I will only pay you if your code work on my computer
