I'd suggest adjusting your budget expectations. You want installation by a pro? Plan on $500. for site visit, install wiring, setup cameras and config of NVR, PC's, mobile devices, etc..
Why do you think you need PTZ cameras? Do you expect to need to repoint the cameras often? I think you'll find it's better to install more cameras instead of PTZ cameras, or perhaps varifocal cameras would be adequate?
A possible set of analog equipment might be:
Hik DS-7204HGHI-SH-3TB DVR ~ $360.
DSC DLT20ABW-V -1080P cam ~ $130. ea
DSC DST2DIV ~ cam $50. ea.
DSC DPWR5A pwr supply + connectors & cable ~ $100.
A pro might tell you to not bother with analog and suggest doing it 'right' with a NVR and IP cameras (which would cost even more).
Hope that helps or at least gives you some ideas for your project.
