Have you considered using stack overflow? It's a great way to have access to mentors and people to help you and if you're working in a particular domain, you will have experts to help you. With one single mentor you're stuck with only what they know.

Thanks for your advice, yes I have asked questions on Stack Overflow and found the response to be excellent, and I plan to use it in the future.

But with a mentor you can ask more general questions, whereas with SO it tends to be more code/error specific.
