You make it seem so easy... Just building/shooting content/ managing one website is a ton of work, doesn't matter what cms you use, I'm sure that model centro will lift some things but a girl taking some selfies etc. isn't going to give you enough content or updates, I think you really need to look a lot further into this
I do think you have a good idea and I disagree with everyone saying stay away from strippers. Set up a date, do a test shoot to see how things go, if good then shoot her for a few weeks straight (make sure all rights are signed to you in releases) etc. but I think you are really downplaying how much hard work would be involved. Nothing in life comes easy.
