You don't have to be a professional web coder, but you must know a lot about it. For example you must understand web development, be good at English, and know how to read PHP and other languages and edit written languages (such as editing a template). You don't have to be a pro coder, but you must be professional and reliable. Having references and proving yourself will certainly help. I will be paying anywhere between $100-$1500 per week in bitcoins!
