nodemcu esp8266 shield design

I'm in need for a ESP8266 NodeMCU LUA CP2102 ESP-12E shield with a step down transformer circuit form 24v to two outputs one 12V with a load of 15 Watt max and the second one 5V with a load of 15 Watt max. The 5v will be used to power NodeMCU and the circuits connected to it's gpios. I also need four mosfet transistors with a similar circuit to this link [login to view URL] the voltage in from this circuit will be supplied from the 12V output of our step down transformer circuit, and each one is controlled by a gpio pin from the NodeMCU. I also want to have a DHT22 on board to read temperature and humidity from one of the gpio pins as well. I also want to have four three pole ph2.0 connector the first one will be ground then vcc and a gpio pin for read or write and I want them to operate at 5V logic. Lastly I need two more of the three pole ph2.0 connector with the same wiring to operate at 3.3V. I know I said lastly but I just remembered that I will need an antenna on board as well. Please let me know your rate for this project. I also wanted to let you know that this is the first phase of the project there are two more phases.
