Arduino Remote Control CAR code

Hi there, I have sorted out most of the code. I just need help fine tuning it. Task to do. (Given Remote control car base - front wheels turn left and right - Back wheels go forward and reverse) Alter or change my current code so that the car follows the wall and maintains a fixed distance from the wall. If too close it has to turn left and rejust and continue following the wall(the wall is always on the right hand side). I am wanting this done by using just 2 sensors. one on the front and one on the right. Please quote your best price, would take less than 1 hour for a experienced programmer. Since everything is almost done.
