I can try composing but you really need to specify what you like/want since "heart pounding chaser music" doesn't tell me much. You should also let me know if you want MIDI or realsound. If MIDI, then it will be easier and quicker, however, if you want realsound, you'll really have to wait. Composing, after all, is not easy, specially if an artist atempts to be more than less unique. Apart from composition itself, in real sound I must take care of technical issues and they are time-consuming, specially if I'm doing classical. Apart from this, it is important to state what do you want - classical, electronical (any genre except techno or IDM) or metal (note that metal is only available as MIDI).
