When growing succulents, the one thing they need above all else is bright light.
If all you have is a north exposure shaded by tall evergreens, this might not be the business for you.
Specialize instead in moss and ferns, those are in demand too.
For other types of services, the site is less important, such as if you're putting on courses, or going to the home of a client to plan and plant their xeriscape.
Greenhouses in particular are important to give the orientation that will give the most light.
Other things to keep in mind are if the greenhouse will be used in winter, and how it will be heated.
Important features to include in your growing area; vermin proof beds to protect the tasty plants from rabbits, squirrels and pocket gophers - they don't call them 'succulents' for nothing.
A bench area to work on, so you're not crawling around on hands and knees, and an overwintering space where planted crafts can be tucked away in a protected bed away from traffic.
Work spaces have to be convenient to use, with lots of storage, and bright light.
I use my greenhouse for a work area, and even on gloomy days it's bright and cheerful.
Benches at the right height for you, so you're not stooping or stretching make the whole experience much more comfortable.

It's going to be important to have a growing area for crafts that are planted and need to get established.
They can be on the ground, preferably on a gravel bed so they stay clean.
I also salvage carpet that is destined for the landfill to make a clean, weed proof ground cover to put flats on.
I've also seen asphalt shingles used for walkways, or landscape fabric.
Nothing is more guaranteed to turn a potential customer off than dirt or sawdust stuck on their favorite pot or hypertufa creation.
The leaves of succulents are particularly hard to clean if they get dirt on them.
There are lots of different ways to grow plants.
Finding out your optimum growing space depends on what kind of containers are you growing them in, and certain other factors, such as the sunshine in your growing area, trees if there are any, and how you'll be selling them.
I grew all my wedding favor Sempervivum in flats, which are called 1020 flats (due to the fact that they're ten inches wide, by twenty inches deep) and then the plants themselves were in 72 cell plug trays.
As my greenhouse has benches that were three feet wide, and up to 60 feet long on a side, this means that I could grow about 720 flats of plants on one bench.
I rarely had the whole greenhouse full of one single crop at a time, but this gave me an idea of my total production area.
Getting an idea of the potential room you'll need for growing any crop is crucial.
If you got an order for 1200 plants of a certain size, how would that fit into your schedule and growing area?
I know, I know; it's math. But if you can get a picture of it in your mind, this helps you figure out all kinds of things, like the profit margin, the amount of soil, pots and all the other factors that are in your control.
One thing that's absolutely crucial for any business is keeping records. See my simple way of putting important information in a spreadsheet here.
Knowing at a glance how much of a particular kind of pot or container, and how much soil you'll need to fill them is gold. The more information, the better. Keep a log book or journal - what gets measured, grows.
