When should I expect to see regular sales from my music?

Hello. I joined this site a few months ago, and I currently have 81 tracks and 76 SFX uploaded. However, I have only made a handful of sales since I started.

For those of you who have had sucsess selling music on here, what amount of tracks should I be aiming to upload? I'd like to know how long it took you to see regular sales from your music.

Thanks.
