Well, a general question like that just allows for assumptions.
You can ask questions like that, that's fine. But as you probably know, the question alone is already an art of interpretation.
What level of development, WGs like Groß, which level of equipment, etc., there's nothing general about that... It really depends on your specific expectations.
Quite casually, I would recommend that you look for the lowest level of development or figure it out for yourself and your own contribution, and then confront a selection of providers you trust with that. The more precise your ideas are, the better you can be helped.
