I think your subtitle is accurate, but here's a suggestion from a complete outsider:

I listened to the first 4 tracks (on Amazon), and clearly you're an accomplished musician. But I think the composing is too complex for someone looking for beats and too simple for someone looking for stand-alone music. The first track (Ha quem ... with vocal) for me worked best as an individual work, and (again, this is an outsider's perspective) this may be where your talent (and appeal) are most prominent.

In any creative endeavor, there seem to be a number of people who make a living by claiming to help others make a living (i.e. the Beat Store providers in this case). Please forgive the pushy and ignorant advice, but I think your most productive route is to promote your work yourself to your target audience (of listeners) and not rely on outside agencies to promote you to other promoters. By writing on The Riff, you're already doing this.
