Simple Single-Layer PCB Design

I am working on a university hardware project in KiCad and I have a deadline in 5 days. I am looking for help with the hardware design only.

The task is to design a microcontroller board using the following components exactly as specified:
• Microcontroller: ATmega16
• 5 V voltage regulator: 7805
• Reset supervisor: MAX707
• RS232 level shifter: MAX232
• LC display: 4 × 20 character LCD, alphanumeric, monochrome, with LED backlight
• Real Time Clock (RTC): RTC 72421
• I²C bus temperature sensor: DS1621
• ADC reference voltage: LT1009
• Chip-select decoder: GAL16V8

I only need:
• the schematic
• the PCB layout
• and the 3D view
