C code for MPLAB C18 project

I'm looking for someone to produce code for a PIC project. The target circuit will be centered around a PIC18F46k20 microcontroller. The project will require communication between the pic and several peripheral devices, specifically: ds3234 rtc (spi), digole serial LCD (spi), ds18b20 (3-wire), Atlas pH board (UART). Code should be well annotated. The most important communication is via SPI to the DS3234 realtime clock module. The second most important is the SPI to serial LCD and is optional but preferred. The others are optional but would be helpful if you can possibly accomplish them. Your bid should specify which modules you intend to complete.
