I am a low voltage contractor that has been tasked to install 750" of 3/4" PVC Conduit on a roof for CCTV Cameras, there are 5 cameras total located on roughly each corner of the building. Being green behind the ears on conduit installation I would like suggestions on how to price said job, any help would be greatly appreciated

The Pentagon?!

Seriously, we would need much more detail. There are roof or wall penetrations and sealing, height and type of the roof, access/ladders/lifts, fittings for cable entry/exit, involvement with cable installation, etc.

It's a lot faster to glue together 75 lengths of PVC (presuming you meant feet (') and not inches (")) across a flat roof than it is to run the same amount down the walls in five separate 15-length installations.
 
I believe you can get armored coax cable or armored Cat6 for your cameras, it will probably be a much faster install to go that route. I don't want to even look at the expansion of 750 foot of three quarter PVC on a roof... I believe the section is 352.44... Even if your conduit is a giant sleeve, you cannot ignore the expansion of that much PVC on a roof which will be on the order of several feet... You will need numerous expansion couplings for that run not to look like a total train wreck.

sounds like a good plan to me. 750 feet of PVC is going to sag a lot too, no matter how well you support it so might as well just use some kind of cable that won't be straight either.

this armored cat6 cable is not cheap but it works well.

call and ask for a sample before you buy though. IIRC, it is not as easy to bend as one might hope.
