Hey,
I'm a gamer myself, which game is it? CS Go, dota 2, cod, rainbow 6, LoL? Just name it, I've played it. I'll be able to produce a montage wayyyy wayyyy more amazing for you than any freelancer who's not a gamer. Why? Because I understand the emotions associated with kills, misses, so on and so forth. I will be able to get effects incorporated in it that will communicate with the audience of gamers as well. I've seen such videos before, so of course I know how it is supposed to be. Let's do it! ;)
Cheers!
