> Ranting about choosing most complex business form and having no money for a consultant is not adequate in my eyes.
You shouldn't need a consultant to open a company. Should be a form and that's it. Maybe an accountant to certify your books, but that's it.
If you're choosing to go with the most complicated way of setting up a company, a consultant probably doesn't hurt.
And you really don't have to. I just went to one a single meeting, signed a single piece of paper, paid 60€ (probably still <100€ these days) and was done with it. But as GP already alluded to: I didn't choose the structure that is very well known to be the complicated one.
They are not trying to just open a company, they are trying to create one the more complex nested company setups allowed by German law.
