I regularly buy Rain Drip supplies from Jerry's. I tend to get about 500 feet of larger hose for $60-ish. Then connectors cost $1-2 each. The smaller lines are cheaper and have many different connectors for different watering methods.
There are so much variety when it comes to developing a cost estimate. It is best to at least have a measurement for the area to be covered
Call them
The pricing is rather low due to several competing manufacturers sold together at Jerry's. And it's better to get an opinion of the area for drip irrigation because they have a high yearly and semi-yearly maintenance in many applications, i.e. head replacement, clogged supply line, etc.
