Already generating income, but i need some advices..

Hi guys,

first of all i want to thank you all cause thanks to your discussions, your tests, your considerations and your success stories i learned a lot and i build up a small business that brings me a monthly income, still not enough to quit my job but anyway it is good, i'm so proud of it.

After this small introduction i would like to ask you some suggestions on my next step, at the moment i'm earning some money with adsense and with some sales.
I've now understood the adsense mechanism and i'm able to let it grow everymonth thanks to "rinse and repeat" and outsourcing.

Now i'm trying to focus more on sales and i would like to understand how can i take it to the next level. For me at the moment the next level are the lists. I need to understand how to build one, how to manage it and how to use it.

I tried to search here some informations and i found them but splitted over more threads. I would like to know if someone can point me to a "tutorial" thread which i did not find or to a good/trusted guide that i can buy.

Obviously if someone would like to put informations on this thread it would be great too!
What i already know is that a good method to build up a list is to give a good free report and ask an email for that and then start with the communication.

Obviously i'm not looking for a magic formula, cause after some months here i know that magic formulas does not exists.

I need only to learn a method that works to build and use lists.

Thank you in advance!

Ps. Sorry for the english but i'm not an native english speaker, i'm from italy!
