Well
Jakers15@, it depends!
Install DAZ, install all assets (houses, furniture, bottles, clothes, hair, poses, people, HDRI's, etc etc etc), learn how to use the program, learn simulations, learn lights, learn cameras, learn surfaces, learn collisions, learn smothing modifiers, learn how to create OBJ's, breaking your head on your desk due to software errors that you don't know how to solve, render, post work, etc!
For those who don't know, it would probably take around 50 days!
But for you it would be around 49 and a half because you are seriously committed to graphic arts!!
Normally, if you already know how to work with DAZ, and have all these assets installed, it would take around 5 hours to create each scene, another 2 to do the simulations and another 5 hours to make the 5 renders I made and the Post work!
Many would shoot some characters with some clothes, hair and poses and not do anything else!
Dforce simulations, Among other things, are very important in the scene!
For example, look at my two spoilers below!
In the one on the left, notice the towel that looks like a normal towel!
The entire effect is done with Dforce simulations, Dforce Magnets, weight nodes, wind nodes and other techniques that make the animation credible!
And none of this can be done with the original asset (original towel), so you have to create an object (obj) and assign the same surfaces and textures as the original but with different numbers of polygons!
In the one on the right, notice how Jessica moves her panties to the side and how Danny pulls down his pants! The same applies here!
All of this takes a lot of time and work to do, but in this case it's an animation, so it takes much longer and is much more difficult than a simple dozen renders!
In the example of your request, I remember having to create a new sofa, some new cushions, some objects together for the 3 characters, to be able to import everything and make the simulations and collisions work!
And by the way, learn how to work with ZBrush to create Morphs for all these things!
