Microchip PIC16 Microcontroller PCB design

Design a BLDC motor driver for a 24 volt 2 Amp 3 phase 'outside running' motor (external rotor motor). Motor specs: 12 pole stator, 16 pole magnet ring, 8,000 R.P.M. 3 phase winding A-B-C-A-B-C-A-B-C-A-B-C all windings same direction. Power input 24 volt Max. 1.9 Amp. To do: Design Hardware & Software for BLDC Sensor less Controller, complete with: - Hardware circuit Design - Software design - PCB Design - B.O.M. List The motor will only be switched 'on and off' by a simple on/off switch. No speed control needed. PCB Board dimensions: width 60 mm. x 60 mm. (or longer if necessary) Possible reference: 'Microchip AN 857'. Looking for a low cost microcontroller, so will look at alternatives
