ethereum fork

We are looking for the modified ethereum based transaction system with higher transactions per second with higher transactions throughput and lower transaction fee. We are looking for the DAG (Directed Acyclic Graph) to be the consensus algorithm which is faster, more tolerant, more reliable and cheaper transactions. The block timing will be the shorter and size somewhat higher to accept more transactions to be processed. The nodes can connect with the network and communicate.
Our main aim is to increase the transactions speed and throughput with reduced transaction fee. If you can suggest other things which can be implemented to achieve the aim we are looking for, kindly suggest.
The deliverables may include but not limited to the updated source code, binaries for deployment of the new nodes, documentation related to it, guide to launch new nodes.
