First I would fill out your profile and add a demo reel. Unless you’re in the CIA, anonymity will hurt you in the professional realm. People either assume you’re not legitimate, or choose to make crass posts, snipe at other posters, and then hide behind a blank profile.
I think what you meant on your post was that you want to make trailers for TV shows and Movies, not that you want to make TV Shows. In the television realm, promos are typically produced by the creative services and/or marketing deparments. As an editor, you want to get in touch with producers that work in these departments. Sometimes inhouse producers can’t do all the work networks need done, so the networks call companies like mine to take up the slack.
So, you’re two options are, find a posthouse that caters specifically to promo producers (Riot! Atlanta would be one) which will be difficult because post houses prefer editors with their own clients in tow, or find an inhouse production department that services promo producers from within a media company (Turner Studios in Atlanta services all networks within Turner Brodacasting).
In either situation, unless you’re an accomplished freelancer with a stellar reel of spots, you’re going to need to come in at entry level and work your way up the ranks, from tape op to avid editor.
It’s better to go the post-house route, because you’ll have access to better spots and more experience producers.
Just my two cents.
