I learned autoit more or less in two days moving over from c++ and python.
Everyone learns differently because they approach the language and their first script with different goals. Scripting language on average are easier to learn, so that is a plus.
You'll find the forum people vary in helpfulness, including myself. However, rarely do people just write code on request.
PsaltyDS post in this thread is a fair reaction to a beginner begging for script service. http://www.autoitscript.com/forum/index.php?showtopic=118836&st=0&p=827134&#entry827134
If you are short on time, rent-a-coder is your best bet. If you are not short on time, then "how long" it takes you to learn autoit doesn't really matter. There are a lot of example scripts. If you load up the script editor, you will find example scripts in the program files/autoit/examples folder that you can play with.
From what I can gather, this won't be a 1 hour project if that is what you are after.
