Thanks a lot everyone for the opinions and sorry for my late answer ( I can't complaint, I was working! ).
About CL I think that is like finding an apartment deal in Manhattan, you have to be 15 hours a day in front of the screen waiting for the dream post to show up, I don't think is worthy, too much time invested and little results, but hey, that doesn't mean that in a lucky day you can find a good client that is going to hire you 15 more gigs, I think that's what is about, networking and contacts lists.
SENATOR mike, I didn't know the " industry leads " nor the " Breakdown Services ", I'm going to research about them, thanks so much, ( even though I've tried hundreds of combinations in Google search engine and almost all of them with the same three words, " Sound, Film, Job ", but never saw them before, really appreciate it ) I think it's going to be very useful.
Robert, I think I understand now what CL could be useful for, even though it didn't work in your case ( neither in mine, yet hehe ) but I think I will continue looking for gigs, you never know!.
John Paul, thanks for your answer, I'm looking for anything that is related to location sound recordings including ENG, events, run+gun, short films, featured films ... ( I think like everybody in slow-times hehe ) and the position ( as long as is not a slavery contract ) is not relevant for me ( don't take me wrong, I'm talking in the sound-related field ). But I'm sure I'm not doing post-production, not ADR sessions , Voiceovers... .
I'm already a member of some sites, but I didn't search about a " local film office ", thanks I will look for it.
Lastly, I know reference and networking plays a huge role on the sound mixer's life, wether we like it or not ( personally I don't like to deal with buro-crap, jerarchy, meetings and meetings that goes nowhere... and I know that if I don't do it, I won't eat, so is very good to know that everyone here have the same feelings towards this statement.
Thanks a lot everyone, if I find a new outlet, I will post it !
