Look Online For Commissioned Artwork

My father really has a huge fascination for different type of paintings and sculptures.  His birthday is coming up and I really want to do something special for him, but I am not sure what I want to do.  After doing a little research I have decided that I wanted to look into get a custom piece of commissioned artwork.  There are a few ideas that I have in mind, but first I need to get the artists recommendation and then we can go from there.  I meet with him next week and I hope that he can create something spectacular.
