Trophy offers are completely based off difference in trophies between attacker and defender.

You are getting closer to the top of the pyramid as far as th9s go. This means that it is much more likely that you will find someone below you then above you. Therefore the trophy offer will be low.
Getting to champs you will either need to be extremelly patient waiting for high offer th9s, hit lots of them for few trophies, or start hitting th10s.
I found I could generally 2 star weak-mid th10s using govaho which is how I was pushing. Many people prefer loonion for 1 star and staying online between attacks.
