Hey Victor, no problem with the English. Most people here have English as a second or third language.
Since we are a DIGITAL DJ Tips forum, it will be no surprise that we’ll suggest you get acquainted with DJ Software. There are ways to try for free. Mixvibes Cross is free if you want to try it without a controller or 14-day demo version with controller. VDJ has a free option (not sure what restrictions). Serato you can install but only use as a 1-deck preparation software without a (Serato-enabled) controller attached I think. Traktor I have no clue now.
Another good point to start looking at is the 2015 Controller Buyers Guide. Very valuable information.
And once you have software and a controller, taking the How To Digital DJ Fast course is a good investment in fast-tracking yourself to efficient practice sessions.
Hope that helps some.
