Help buy me a MacBook pro 512gb ssd

I am a software engineer from Africa and a technology enthusiast. Recently I have picked interest in developing for iPhone and xamarin but lack a standard tool for development due to their humongous price.
I will be hosting free apps on the Apple store and PlayStore that will help people in Africa and the globe tackle daily problems. I will appreciate if you help contribute in buying a new or refurbished macbook-pro with 256gb/512 gb ssd no matter how small
