im going into 12th grade and need a senior project. just how hard would it be to build an acoustic guitar? and how much do you think it would cost......
Check out the Guitar Building and Customization board, especially talk to CorduroyEW, hes a professional luthier and builds acoustics for a living. The only setback besides the knowhow is the tools are very expensive. Contact him and he can explain it all in much detail.

Martin sells an DIY acoustic guitar kit for around $500-600. Check out Musician's Friend or American Musical Supply.
