Help with Garden Irrigation Project

I have a 20x30 garden that I want to irrigate. I have a couple of different types of sprinkler heads that are circle and rectangular spray patterns. My problem is that I don't have enough pressure to operate them. I bought a booster pump from harbor freight but it still doesn't have enough pressure. The heads do not even pop up. I have the heads connected in line, 6 total, with 1/2 inch pipe. The supply line is a 3/4 inch garden hose that is hooked to the pump. The pump is rated at 71psi, according to the book, but the outside of the box says that it has a max psi of 36. So I am not sure what it is really. The hoses on the pump are 4 ft each so what ever the psi really is should not have any loss when it enters the 1/2 inch pipe to the heads. What do I need to do to get this to work?

Micro-sprinklers or drip.
