Hi there coldfact. Welcome to Electronics Point.
We don't allow direct advertising here, so I've edited your post to remove it.
However, we do allow replies from commercial entities where such replies are direct answers to questions asked, or which would be ones that a disinterested third party might provide.
Having said that, we do have numerous people showing up here wanting things designed or manufactured, and there are very few of us willing to enter that arena.
If you were to reply to them "I do this commercially, if you are interested you could contact me...". That would be appropriate.
The whole point is that you cannot be here to drum up business, but it is fine to (on direct request) tell people where they can get services performed.
The penalty for advertising is typically having your messages deleted and getting banned, which we really don't like to do.
Let me give you an opening here... What sort of things do you do for people in your studio, and how is it equipped?
