Provide a step by step solution for the following math problem: Timothy decides he wants to start living off the land.  He buys 30 acres of land for $20 an acre.  He then builds himself a large house for $120,000.  After that, he gets himself 20 cows for $1000 per cow and 100 chickens for $5 per chicken.  The last thing is solar panels which take 6 hours to install with an installation cost of $100 an hour and then a flat fee of $6000 for the equipment.  How much did everything cost?
