Prime Broker for $1M AUM without minimum charge per order

Can someone please recommend a Prime Broker that offers reliable FIX API for automated trading without minimum charge per order? My AUM is slightly more than $1M and I trade 2M+ shares per month. Monthly volume should grow proportionally as the AUM of my startup hedge fund grows, which is likely to at least double given our high sharpe ratio. Thanks in advance for any good advice.

 

Does a minimum per order of $0.35 also count in your criteria or is that negligible?

 

Any minimum per order is not favorable for my strategies, especially a minimum of $0.35 per order is way too high.
