Narrative:

Small aircraft X parked at the FBO called for taxi instructions. I was working ground control, taxied the aircraft to runway 36L, via 'a' -- the pilot read back 18L via 'a.' I did not catch runway 18L. The pilot did not join 'a' (taxiway) however crossed runway 36L at intersection 'B8' (about 3000 ft from the approach end). I then observed him crossing and tried to contact him. He did not answer. After the third attempt, he answered. The aircraft was instructed to hold short of runway 36L. He caused confusion and had trouble on his arrival to the airport earlier. On departure he did not contact departure control (orlando TCA) and climbed to 2500 ft, when initially only cleared to 1500 ft.
