To minimize the amount of sawing I needed to do I had the home center ( I used Loews) to do most of the long cuts. Since I was not sure how wide I was going to make the shelves I left those 6 cuts to me, but you could have the home center do those cuts as well. Both Loews and Home Depot both have chops saws but its kind of hit/miss if its working for they have staff around that knows how to use it so call and ask before you make the drive. Other home centers and lumber yards may also do the cuts for you. Usually they give you 2 cuts per board and charge 25 to 50 cents per cut after that but I have seldom been charge extra cut cost on projects. Having them do the cuts also makes transportation a little easier as the resulting cut wood will fit in most SUV/Crossovers.
