I have worked in network television for half of my 41 year career. You are a post-guy that specializes in production not necessarily composing and producing music. There are numerous great sounding commercial music packages sold by many different composers/arrangers that specialize in creating music. I would suggest looking into a commercial music package. One that I liked when I was at NBC came from Nashville Tennessee (where I have been for the past month) called 615 music. 615 just happens to be the area code also. Their stuff sounds terrific. Great writing, arranging, great mixes. So you should contact them. There was another music library we had at NBC DC that were very artfully crafted nearly identical " sound alike " package. Every tune sounded like a hit rock 'n roll tune that we all know. But it wasn't. Certain chordal structures were inverted and changed so as not to create copyright infringement. But they were so close, you can actually sing the lyrics of the originals song to it. I still have a copy of some of those somewhere? I use them as an example that when people are worried about anybody hearing their music because they don't have a copyright yet, I tell them, it doesn't matter if you get a copyright if somebody wants to steal it. And if somebody is brazen enough to steal it, they're going to have a lawyer on retainer.
So utilizing commercial music packages is a perfectly acceptable thing to do. You are a better cook than others that have to rely upon TV dinners. You know how to put all the wonderful fresh ingredients together to come up with something far better. Having a dynamite music package would also further enhance your quality of delivery. And yes, I think they ship to Canada also.
That's the 411 on the 615
