I pray all is well. Earlier this year I came across this great website called One True Media that helps you easily make quality trailers for little to no cost. Trailers 30 seconds and under are free, and trailers longer than 30 seconds require a subscription of $4 a month.
More recently, I found out about Jewelbeat where you can purchase a license for music for as low as $1 a track. You can use the music for things like trailers, dvds, and so forth. This will come in real handy for folks who are like me, and want to add that epic feel to a trailer with some great music.
I hope you find these sites useful, both from a quality and budget standpoint. Until next time, keep creating, and if you know of any other great resources, leave a comment and spread the wealth!
