Hello Dear
I hope you will be fine. We offer our services for your project. Let me introduce my company, we are professional customized software developers. we did a lot of software development in local and international market since 1999. We develop desktop applications in vb, vbdotnet, mysql, mssql server 2008 and web application in php,c#, java etc. We can also develop android APP.
I suggest it should be in three formats like some portion on desktop, some portion on web and some portion on android. This way you can get proper benefits of software application. It should have also a facility of SMS when some one get service or his vehicle expected oil change date. These are my suggestions and we can do for you if you will give us a chance. This is how may we get closer to finalize the project.
thanks
