Arm7 microcontroller developer.

I'm looking for someone who can guide me which arm7 development board I should get for a small project. Must have a knowledge in development of arm7 microcontrollers and writing the software. Basically is a controller for an electric actuator. There are 8 inputs, one of the inputs is RPMs of an engine. 8 inputs and 1 output to control the actuator. I would like to use a board which has an LCD. On board commands to make adjustments like a selection key and ( + / - ) functions. It will have about 16 different modes in which the program can select from. Thank you for the interest.
