I don't want to be a party pooper and hope you won't throw bad eggs my way, but PLEASE be very careful when you use stock photography as part of your logo/brand, and other mediums in your business.
There really is a fine line with copyright infringement, and although you have purchased it, or plan to, there are still licensing rights to the owner, unless you come to agreement with the owner to transfer/pay for the actual copyright of the image.
Here is an article for source, and you can also find more information online:

Good luck to you!
