Architect to Design Office Layout

need an architect and designer of office space that can take our blueprint of 2800 square feet of office space and design a layout conducive to our needs and get the most out of that space. I need someone w/ experience that can capture the image the lighting, the coloring of walls that would make our office comfortable and future looking, but with the idea in mind that all items you are going to use to decorate the place with must be inexpensive. We normally buy our discount furniture from IKEA. pls show sample renditions of your work. Thank you.
