Interesting...hard to throw a price out there. I would be tempted....all mine are in the basement so I would just rent the basement with a dep. Part of the deal would be i will be home and upstairs and not bother them. My basement has a full kitchen/bar and bathroom so everything they could need. Also is a walkout so they would be able to enter and exit the house without leaving the basement. Them knowing what you h ave could worry a person but what's different than the average dude on cl coming and seeing a collection. Plus that's why security systems are handy. You would think the employees would be a little trust worthy but who knows. Will be interested to hear what you decide to do
