Combine espalexa and wifimanager libraries in esp8266 project

I have a project of ESP8266 wifi module, in which I am using wifimanager library to connect the module with wifi connection. I need to add Espalexa library in this project to make it compatible with Amazon Alexa. Both these libraries are conflicting as they both use webservers. I need to combine both in my project. Freelancer should have expertise with ESP8266, Arduino. Quote near your expected price and not far from it.
