Programming assistance for Pixhawk Autopilot and 8 + 2 motors

Hi, We need a consultant in the East Anglia area (preferably in Catfield, Norfolk) to help us connect up a Pixhawk Autopilot to 8 (MT 3515) motors + 2 x 10Kw motors. Happy to pay travel, accommodation and for time, could be weekend or week day / nights. Programming / hacking knowledge in PX4 would be a great benefit. regards, Haslen
