Welcome to the board Eva - yes there is plenty of information here!
Regarding finding schools/mentors can i suggest you spend a month or so reading everything you can on this board and maybe even start paper trading (simulated trading) a market you are interested in - this will give you a feel for trading and what you need to know and will put you in a good position to have a better idea of what you want and need from a school/mentor, the questions you need to ask before committing and so on. If you have time join in with the chat room during market hours and watch what traders are doing.
There are hundreds of great posts and threads on this site and plenty of great posters. I am reluctant to nominate just one but if you read everything you can from "Walter" (the Chimp) and then follow his workings in the chat room that would be a great start. Walter has posted many very thoughtful and coherent threads where he explains his reasoning, testing, results and so on, so even if you end up not following Walter's style of trading you will get a great guide to a very robust process to employ in setting up your own trading approach.
There are others who have posted some threads that are well-structured from a learning perspective too: BrownsFan019 on trading with candlesticks, JPerl has an amazing series of threads on Market Profile, Soultrader has plenty of videos showing trading in real time, there is a massive thread on the application of
VSA with consistent contributions from PivotProfiler. Now there are plenty I haven't mentioned too, just too many!
Enjoy!
