Kamailio (Dispatcher) /Asterisk in AWS

I am looking for someone with experience in Kamailio/OPENSips (Dispatcher module), Asterisk, and AWS. Currently, we have three Asterisk servers on AWS and would like to place a Kamailio/OPENSips server in front of it for load-balancing with dispatcher. The project is to setup and configure a Kamailo/OPENSips server as an AWS EC2 instance and correctly route phone calls between the Asterisk servers. These Asterisk servers handle calls for other Asterisk servers located remotely. They do not handle individual users. I will provide the servers and IPs to work with.
