AutoMTA pro - cash and time

Im currently suiciding with AutoMTA (usually running 24 hrs a day but im experiencing alot of crashes, probs my settings, havent checked yet) but how long do you reccon it will take for 74 - 94 mage and then 94 - 99? Also, how much cash will this raise me?

edit: Think I might switch to Autoboltenchanter at 94 when I have enough money to make a decent bit of cash from it. I've heard its quicker and mroe reliable.
