ATMEGA328 code required

We need a code written for ATMEGA328P MCU in Atmel Studio. Code Structure: - Two buttons : Button 1 & Button 2 - Four LEDs : LED1, LED2 ,LED3, LED4 and LED5. Functionality of the Button : Button1 Used for : - Starting the system. - Selecting Sequence1 and Sequence2 - Stopping the System after Long press of 5seconds. Button2 used for : - Starting the Sequence1 or Sequence2 after selection - Stopping the Sequences. LED1 & LED2 for Battery indication if Good - LED1 is ON or Low Battery - LED2 is ON Operation: When Button1 is pressed if the Battery level is Good only then system will work. Now at good battery Level, When Button1 is pressed LED1-ON(power-on Indication) and LED3-ON(Run Sequence1 Indication). Pressing Button1 again will help to select Sequences between Sequence1 and Sequence2. Once the specific Sequence is selected , pressing the Button2 will start the sequence and pressing it again will Stop the running sequence. Once the sequence is STOPPED , you can select the sequence again and then run it. When you press the Button1 for Long press of 5 seconds, the system will switch off. Sequence1 - Blinking LED5 at 1second Sequence2 - Blinking LED5 at 0.5second. Please write to me about your queries and how you can do this. Time-line is 2days.
