WP Back end Optimization

Need a WP expert to help streamline and optimize our backend. Our site aggregates much content. The processes are straining the server. The server load could be greatly reduced VIA optimizing the processes and ‘cleaning them up’ so there is not excess server load. You would take a look at the system and processes we are utilizing, and determine ways to optimize the server load while maintaining the presentation of content. Need LOW PRICE as we are in an investing and struggling phase. Would result in more work.
