I dont know about your lawn, but your flowerbeds could be set up with a drip irrigation system and you would waste less water and do it yourself easily. Also, it is definitely the cheaper of the irrigation systems. I was pricing a simple set up for my house and was looking to spend under $200.
Link Here. This stuff is sold at the Home Depot and it consists of a 1/2 hose you can bury and the smaller mircotubes or spigots that start as low as $1.00 each.
