getting drawing boards from diy store7carpinter? (mdf pref or equiv)

hi.

moved to area near velez malaga for 4 months to draw and paint etc. i need to get boards cut - varying dimensions, similar to just going into b&q at home and pulling out sheets and getting them chopped down to my dimensions by the dude with the big saw machine. is there an equivalent here? drove around velez malaga industrial estate and as enjoyable as it was, i didn t quite know where to go, who the hey and what the where etc... just want to go to one place and get sorted quickly. cheers. albert ryder

also any good places (ie skips) for scavenging cardboard7off cuts of wood etc. great for collage.
