DC power circuit with LiFePO4, Peltier, Battery life indicator sub-circ, on/off, rechargable with pcm/bms

A [url removed, login to view] LiFePO4 single cell power source must provide DC power to a series of components. The components include a small peltier (5V 1A) and a simple 5 LED battery life indicator sub-circuit. The circuit must also integrate a PCM/BMS for the LiFePO4 to manage charging and discharging and the charge input port must be wired to a [url removed, login to view] barrel jack (female). Last but not least, a simple push toggle ON/OFF switch with LED backlighting must turn the circuit on and off. In addition to the bid, I will provide materials for the prototype up to $100.00. I need a fully functional prototyped circuit and the schematic to reproduce it. I will also need a list of any outside parts you used and where to procure them. I have already selected the on/off power toggle, DC power cell, peltier, BMS and [url removed, login to view] female jack and will ship them to you. I don't have enough experience in this field to assemble them together, so I need someone who can!

PS: I think need a DC-DC power supply to transform [url removed, login to view] into 5V for the peltier. If that's true, I will also send a DC-DC power supply that I prefer for this build.

I also need to confirm that the system can run for at least 12 hours. Peltier does not need to run at 1C, but lets try and get close!
