Built-in storage to maximize space

I live in a 1000 square foot house with my two boys. Space is becoming an issue and I'm looking for ways to maximize our space on a budget. Currently I have a desk in our small kitchen/dining area that we use regularly but takes up valuable dining space.  I would love to save space and create a desk/work area built into the wall to gain a few extra inches of depth. The area is about 4 feet wide but only 15 inches deep (current desk sticks out from wall about a foot). Another space saving project is for the tiny entry way to add a bench or maybe just a shoe and coat storage area. I also would like to remove a window in a bedroom to gain wall space. I'm looking for a carpenter that would take on these somewhat small jobs, has an eye for design and clever use of space and be considerate of a limited budget.  Some electrical work would also be needed.  Any suggestions greatly appreciated!
