Can Anyone recommend

I have purchased a Volvo QL trim tab 300mm kit and would like to get them fitted to the boat but have the following things that will need to be done at the same time for them to fit.  The boat is a NZ ally extremeboats 665 Hardtop (current boat name in their range is 650 gameking).  I need to have the transcuder mount relocated, the water intake for a deckwash (which I currenlty dont have) modified/moved and a small bar used to route the transducer cable moved.  I would also like to explore the possability of mounting the tabs onto a 10mm think plate that is drilled and tapped as to avoid putting 8 extra holes into the transom.

Can anyone recommend someone who if familar with fitting the volvo ql trim tabs and can do the ally work as well??
