Looking for an Unity expert (with some shadering and 3D modelling skills) to optimize HUM3d models for Unity Android game

I am looking for an Unity expert to optimize some vehicle 3D models (bought from Hum3D), for a mobile Unity game.

IMPORTANT! I need someone that has done a similar task before and really knows what he's/she's doing, not trying it out for the first time.

Skills required:
-Unity knowledge,
-Skilled at mobile game optimization
-Shadering,
-slight 3d modelling knowledge,
-lighting,
-slightly animation skills;

What needs to be done overall (we will elaborate the task together after I buy the models):
-optimize the Hum3d vehicle models for a mobile game (they already have mostly 30k poly interior + exterior), which includes texture and shader optimization;
-instrument cluster: separate needles (ready to script the instrument cluster);
-lighting of the instruments + lighting of every button in the interior;
-setting cameras and project them on the vehicle mirrors;
-lighting set-up (Day-time running lights, low beam, high beam, turn signal indicators, rear parking lights, brake lights, turn signal, reverse lights)
-any shadering optimization;
-windshield wiper animation;

What we exactly need to do can be established after I buy the 3d model from Hum3D.
