Acting : Voice Over by Mark Mccormick

Hi my name is Mark and is looking at breaking into the voice acting profession i have been involved as an actor in TV/Film for the last few years and still plan to continue doing that. i have done several demo's which have shown some interest and one company asking me to do a two minute demo to send to them. i have decided to book a recording studio in Manchester but will need someone to direct me so i can do a professional job can i ask if anybody know's of anyone who would be able to come in and do this for me? also any tips on how to find the perfect script to use for the demos i will be doing? many thanks for your time Mark
