Battery driven motor circuit and PCB Design

1. Task Design a power circuit for using "ESP8266 ESP-12e" to control "GA12-N20 motor" with single "18650 battery". You shall be able to work on this project if you have done battery power circuit design and enjoy working on, say, Arduino, Microchip, TI MSP430, or any such micro controllers. Search these terms on Amazon or eBay or Google for detailed specs. 2. Requirements: 1) I need to control TWO N20 motors independently rotating in any direction with ONE ESP8266. 2) I want to use ONE 18650 battery (2600mAH x 3.7V) to drive the whole system, including Wi-Fi controlled through mobile phone. 3) I need to make sure the stand-by leaking current to be extremely low -- the single 2600mAH x 3.7V battery shall last at least 3 months without recharging IF we only drive the two motors 1 second per day but at random time with a command from mobile phone. That is, when ESP8266 is in "light sleep" mode, the TATAL power consumption, when measure from battery output, shall be less than 1.2mA. (See [login to view URL] for definition of "light sleep".) 1.2mA x 90 days x 24 hours = 2592mAH 4) I need to have all the additional circuits on a separate PCB of "exactly the same LxWxH" as ESP-12e. I need it to be as small as possible and as thin as possible. 3. Expectations You are not expected to write product quality software. You just need to have a simple sample program to demonstrate your circuit working as expected. That is, this project is more focused on circuit design and PCB layout. 4. Deliveries: 1) a video demonstrating your working system on a bread board. 2) a detailed design doc with schematics, parts, calculations, and working details. 3) your step-by-step guidance for me to follow your #2 delivery above to reproduce your #1 above. 4) PCB layout, with which I can directly send out for PCB fabrication. Please bid with task break down and time estimation.
