PCB and Schematic design

This project is a fully of typicals designs where usign a microcontroller, pwm output with 2nd order rc lowpass filter this signal go to op amp non inverted amplifier configuration, the op amp output must be boosted (with bjt or jfet) I need 100ma minimun current in the 0-10 volts output.
Requirements

• 2 pwm outputs
• 2 RC 2nd order lowpass filters
• 2 non inverterted op amp configuration, output must be boosted (bjt o jfet)
• 2 relays SPST (with transistor bjt and protection diode)
• 1 relay SPDT (using 2 relays SPST with transistor bjt and protection diode)
• 2 RS485 (using pcb module)
• 2 GIOP
• 4 Leds
• 4 push buttons

The time of realization is 7 to 10 days, the design software that you can use is Eagle or Altium.
