Program for PC to download SMS text messages from all iPhones

Very important! Read this very carefully please and then place your offer. I want to hire one professional and experienced IT engineer – especially with iOS devices (all iPhones). Before we start to cooperate, I want to check your iOS projects, experience, references and your website. I need some simple program for PC (Ms Windows 7 and all higher versions) to download/transfer all SMS text messages from all iPhones to the local file *.vmsg (Microsoft Lumia standard) on PC. I will provide the VMSG file architecture. The program should be developed in C# language. The name of the program is: SMS EasyExporter for iOS. How should this program work: Any iPhone user connect (via USB cable) smartphone to PC and execute this program on PC. The program automatically downloads all SMS text messages and save the file on local Windows desktop. The most important are the communication libraries for all kinds of iPhones: iPhone 3G iPhone 3GS iPhone 4 iPhone 5 iPhone 5s iPhone 6 iPhone 6S iPhone SE iPhone 7/7 Plus iPhone 8/8 Plus The program must support all below iPhones. I want my program to work on PC with Windows OS without iTune installed (without iTune environment). I already have some program but this program doesn't support iPhone 5-6-7-8 and the source is not good. You will check this program. The GUI in the new program will be the same as in old program. Very important! At the end, I want you to make the videos with all iPhones (3-4-5-6-7-8) and show on each video that all types of iPhones work good with my program. I expect: 1) good and stable working program on PC (Ms Windows 7 and all higher versions) 2) fully legal source 3) your compiler version 4) good and fast communication between me and the programmer 5) keeping the deadline. Before the payment, we will check the legality of the source code and see all your videos. If you don't fulfill all my requirements, then please don't place your offer.
