Hi, as far as I understand your project, you want to build an operating system. it does not cost 250 usd. it costs much much more, and it needs a skill-able team of engineers. I can help you with guidance, what do you need and I can provide you consultations - feel free to ask. But be sure, this project is costly. Best wishes Yuri
