You are on a budget so I suggest you make an appointment with home depot and with lowe's and see what their kitchen designer can do for you as it can be simple one stop shopping to get some ideas and see some products that might work....I see your MC in on the DW, first look into the MW fan set up; it is economical and very functional in a small space.....see what is out there before you start into this project....take you time, enjoy the process and see what you come up with.
