Do you need a mentor to make it on-line and are there any good ones out there ?

Having bought products ,ebooks and systems and done nothing with them over the years . I have at last started to blog . Blogging is a great tool and i really enjoy it. I got into blogging through being on a mentoring program. Needless to say it was not a good program and I did not earn millions as the mentor suggested but I was introduced to blogging.

I have been in a few mentoring programs and tried a few courses but there always seems to be one thing lacking in these programs and that is personal help when things go wrong. i know that with all courses or programs the teacher shows you exactly the way they have done things and then it is up to you to take that information and adapt it to your own personal work. Great but what happens when
A the tech side of it goes wrong and you don't have a clue how to put it right. Most programs have help sites with them but they don't always have the time or money to help you personally . So you could get stuck on something simple but you don't know how to put it right .
or
B you have no idea what you are doing wrong and need somebody to look at your site/blog to tell you what is the next thing to do.
So are there programs out there that can provide these services and do you realy need a mentor to make it on-line ?
Let me know if there are and what are the best ones or the ones that do help you with these problems and help you to make money.
