Making NodeMcu connected to arducam to Deepsleep Consuming Micro Amps

I need an expert in electronics who can put nodemcu v2 board to deep sleep which would consume in microamps without modifying the board. This board is supposed to be powered with a 2500mah lipo battery and should last for more than 6months. A 5mp Arducam is connected to this board which would take at least 4 images a day. The working is nodemcu wakes up takes an image and sleeps. Other suggestions are also welcome which could include a different board for consuming less power. The parameters should be small size, 6months working on 2500 3.7v lipo rechargeable battery, should support Arducam or other cameras, But most importantly it should have lest amount of electronic components as this needs to be assembled by someone remotely without any knowledge of electronics thus no soldering.
