Please, see the first message in this thread. We sell electricity and have buildings for rent.
You don`t need to invest in "don`t know what". Write me in PM, what do you want for your needs.
And yes, there are no pics for security reasons. But its for the first time..
Making contracts, all procedures and conditions are clear.
How would a picture from inside possibly be a security risk? Expected to show you have the space and heat exhaust is very fair to ask.
Also you should have a real security system, if your only security measure is trying to hide it that is not best solution.
