I think would be useful to know more about what you are after and what style of music you want to be writing - pop, rock, funk, jazz, blues, country, edm, hip hop etc. etc.
Is it really just the "beat" or are you really looking for the actual "music" to put lyrics and sing to?
I can probably help you out with bits and pieces I have started and are just laying on my hard drive but a little more info would help me give you what you are looking for
