You are right! Lots of buyers have no idea how long it takes to make a really good model and sometimes they don't know what they want or need.
There are lots of buyers that just throw a bunch of buzz words, (they heard out there) but have no idea about the actual process.
Someone needs to be there to educate them and figure out what they need and want before wasting artists precious time.
I want to be that person. Judging by how many odd job listings are being posted it would seem that no one is actually screening them or checking if clients even have an appropriate budget in mind.
