Are there any freelance landscape designers out there?

I'm looking for a side income that I can do predominantly at home, I'm trying to get into freelance landscape design. I'm trying to gauge whether or not this is just a title I dreamt up or if anyone is actually doing landscape design plans without installation.

For reference I have 5 years of horticulture experience in my area and am planning on attending a permaculture design program this summer... So not totally unqualified but still
