Red face exhaust fan on first floor of two story house

I understand that installing a bathroom exhaust fan is not difficult if you have an attic above it. However...

I need to install one in a first floor bathroom. I have a spot light that I can remove and install the fan/light. So that solves the electrical issue.

My questions are:
How do I vent it to the outside?
Do I have to cut up my ceiling to put the duct work in? Can it go out the side of the house, or do I have to somehow get the ductwork all the way up to the attic?
What if the joists point the wrong way, I know I can't cut through them?

Thanks for your help.

first, remove the light and see which way the joists run. this will determine your options. if there is a cavity allowing access to an exterior wall, you can run a flexible pipe to a sidewall vent cap. i would spot my hole outside then fish back inside to catch the flex and pull it back.
if no horizontal access is available due to headers, beams, etc, you will have to find a way to go up to the attic, for instance corner of closet, etc that lines up with fan location. if there is a basement or crawl underneath, you can go down and out
