Nope industry running on small margins and client with atypical expectations who probably doesn't want to pay for what the extra work costs
Software guys don't know what small margin means.
I think you've picked some creative fields but haven't actually identified voids to fill. What are you offering that S-Frame or Revit isn't? What drudge work in particular do you think you can tackle that no one else has?
If you can identify some specific voids to fill, go ahead. but I think those voids you identified are likely your unfamiliarity with the industry.
But if you've got something, go for it. Just research first, because right now it sounds pretty nebulous.
