Room wanted around Irvine or ayr area

Hello I am a 45 year old professional looking for a room to rent in a professional place around the Irvine/ayr area while working in the area for at least 6 months but possible could be for longer. The room would preferable be pay weekly but monthly is fine , all bills to be included En-suite is a must References can be obtained from my employers if needed.
Regards
Dave
