Hi, am a professional and experienced custom windows software developer with over 10 years, I can develop your Car Rental Business software in .Net within 5 days since I have developed this kind of project before and I can show you the demo, because I need ratings at this point I'll do it for $100, no releasing any payment until the software is done to your satisfaction. I will be very grateful if you consider my bid, kindly message me for more details and further discussion, thank you
