purchase drawings and the rights to that image

I have several images in mind and need someone who can draw in realistic ways - especially people, figures and faces with emotions and is comfortable drawing exactly what I have in mind. Details will be discussed when I find appropriate artist whose style I like so I would like to see samples of your drawings, you don't have to send any images it's enough for me to see over live chat or collectible image photo of what you do. You can negotiate your prices with me and I will want to purchase a full right to the images as will use them further for commercial purposes. I need someone honest and confidential, nothing dodgy but just to make sure you won't steal my ideas when I present them ;-)
