Like they say about when someone has to ask the price, more than you can afford...
Honestly, with the little info given, you aren't going to get much valuable info here. There are way too many variables to factor. You would need someone very seasoned in running rigid with all the right tools and first hand knowledge of the site to give you anything close to a ballpark.
Having ran a minimal amount of rigid myself, as well as a little more EMT, ENT, LFMC, etc, rigid will by far take much longer than any other conduit. Using compression fittings will save you time, but depending on your labor rate, they may cost more than labor. Again, too many factors.
