Senior and Vet would like sprinkler system install

Have home with bare dirt yard with only recent grass seed put down. Considering possible irrigation line install depending on cost. No trees, flowers as it is all flat open area so will be easy layout. Half-acre lot. I can also help or rent equipment that would make installation easier if that would help and you have the expertise.

Cost is a big factor because I'm on a small fixed income. If you would like to discuss it with me, I would like to know your charge and what it would involve. Thanks
