actually the OP asked very directly for schools where it would be possible for a arts degree and science. One of the finest in those two areas is VCUARTS?VCU. , by mentioning that
VCUARTS is both a top #2 art school and VCU is a renowned science/research school just perhaps I have shed a light on some new information that the OP is welcome to explore further.
The OP also makes mention of the business of Art, sales etc and VCUARTS is excellent for this.
