I need a sound engineer for my wedding

Hi. We've got our wedding next year (13th July) and it will be hosted on our farm. We've got three marquees, and each will have Bose PA speakers. I need someone that is reliably good with PA/sound tech to be in charge of the microphones and playlists between the different areas of the wedding. It will be a fairly simple and easy job, but we just need someone to rely on to make sure microphones are switched on at the right time and given to the right people, and the right music is played at the right volume at the right time. I will be providing the speakers and cabling etc. It would be great to have someone local who could pop down the day before to familiarise themselves with the setup. Thanks!
