Need mailboxes mounted on brick surface

I have two 3-cluster mailboxes that need mounting on a red brick surface of my building. The space is narrow, but I believe boxes will fit - first cluster on top and 2nd cluster underneath it. A set of 3 vertical doorbells may have to be shifted somewhat for boxes to open properly. I guess the whole thing shouldn't take more than 2 or 3 hours, maybe less depending on experience. This will require some drilling through red brick. Please have your own tools and/or whatever else you'll need. I can only pay $150 cash for this project. Please email if interested in helping us out with this. Thanks.
