I am happy to discuss invented languages for print media, video games or movies. I do have a day job, so the normal production schedule for television might be difficult for me to keep up with in a timely way if you need a language that will see heavy use.
I normally charge hourly rates, with different rates for basic development vs. dialog translation, but we can discuss other options. A base grammar and vocabulary of 800 or so words takes me about 80 hours. It could go longer or shorter by ten to twenty hours depending on the nature of the language we're creating. It's best if I have three to four mounths of lead time to get the core language in order before starting translation work.
To get multiple invented language proposals to choose from, consider posting a job on the Language Creation Society's Jobs Board.
