Hi Xavier,
That depends on different factors, in order for me to offer you the best deal I would need some info like:
-Estimated budget available.
-Number of tracks needed and lenght of the tracks.
-Delivery dates for the music.
-On which platform will be the game released.
Feel free to PM me or write me an email to infoehj@musicvortex.nl for more info.
Cheers!
