Question about archViz Program

Hey everyone!

Just a little background. I'm a 25 year old entrepreneur who has started his own furniture store as well as trying to branch into the interior decorating aspect of things for my wife and sister.

I'd like to have an application developed using UE4 that will allow them to place any product from my website into custom floor plans to show clients how things would look side-by-side.

Any kind of idea how much this would cost for me to get developed? Even if it's a desktop only application, I just want to have something that decorators across the country can use to sell products from my site in realistic settings.

Thank you ahead of time,

Jordan
