Residential Speaker Cable Installation

I'm in need of an experienced installer to install copper speaker cables for a 4 speaker setup in 2 different rooms separated by a 4.5 inch brick wall in a residential home. All materials will be provided (speaker cable, trunking etc). For one pair of speakers the cable will have to go into a loft void, through a room in the roof and through another void. It then needs to go down behind some plaster board linings and then through a one U pattress and plaster box fitting into an amplifier. Lewes East Sussex
