Not trying to be a jerk here, but unless you're a seasoned tv writer (and if you were, you wouldn't be asking this), it's pretty unlikely that something you dashed off quickly turned out that well. Maybe it is good, but to get produced it needs to be great. Have you read the Game of Thrones pilot script? That was pretty good, and without an option or a name writer attached it has to be better than that.
Also, you did this in the wrong order. You get the option first, then you write the pilot, unless it's a pure spec not intended to be produced, e.g. written just as a writing sample to get a staff job.
Almost every writer and showrunner in hollywood has a "passion project" like this that they would love to get made one day. And just as often, they can't do it even with a few shows under their belt and tons of connections.
Not sure why you're asking this on a startup news site. If you want, put on your flame-resistant armour and ask this again at in the forums at donedealpro.com. Post some sample pages there for critique. You'll get a lot of flak, and there's a lot of trolls on there, but you'll also get some good advice from people working in the industry.
All of that said, I hope you prove me wrong. You're right about one thing, it is a great series and would be a perfect fit for TV (well, except for budget, some of those settings would be unfilmable due to expense).
If you want, email me 5-10 pages from your pilot and I'll be happy to give you honest, constructive notes.
