Alexa Smarthome Code and Configuration for Link with ESP8266

I have made a hardware device based on ESP8266 to be a smart home device. I need you to code and configure the system to be a production ready Alexa device and eligible for "Works With Alexa" certification. I have working code to configure and connect the device to WiFi and turn it into an Alexa device (using the Fauxmo library). However, this needs to be configured for a production ready product I can sell commercially. The ESP8266 code can be Arduino or Mongoose-OS based. The rest of the code will need to be placed on my AWS account (I also have Login With Alexa/Amazon Developer/etc accounts that are ready to use). The system will be "Alexa Smarthome Skill" based. So the user can enable the skill on their amazon account and discover and control the account. Please let me know if you can help. I am looking for someone with prior experience with this sort of project. I am happy to share the code I have already created, though it is hacked together to be a working prototype.
