I've working alone in my web business for quite long, and I'm willing to start a bigger project that will need to involve more coders.
I hire frelancer from time to time, but I will need now more than one coder and designer working together in the same project. What could be the better way to manage this team of remote workers? is there any web solutions to manage that? How can I do it knowing that they will not steal the project?
how, and what python can help me setup a business?
It is most unlikely that Python can help you set up a business. Starting in business you first need to find an idea that you can market and people will pay for. It could be a manufactured product, food that is grown, or some type of service, but you need the idea and a business plan first.
A business is selling either a product and/or a service.
You must come up with the idea then do some work towards creating the product and/or service. Then you must sell either the product and/or service to someone or even sell the idea to someone.
Python, or any programming language can be used to create the product, to create the service, to manage the business and/or to manage the service. It can also be used to create a demonstration which represents how the product and/or service would work if it was fully implemented.
