Startup in Madrid

Dear all,

living in Madrid, I have been playing with the thought of putting my own ideas into the startup of a new business. I do have quite a picture in my head already regarding what I want to run as a business... but having been employed so far I am aware I am lacking experience to startup all by myself.
Therefore I would be very interested if there is some events or agencies specialised in giving guidance to new potential startups about what to consider / watch out for, etc. Does anyone of you have advice on this please? I keep hearing of startup events in Madrid... but haven't found anything recent on the internet yet.

Thanks a lot for your suggestions :-)
