Outer Limits 4x4 Board

g'day, A mate and i want to cut my gq wagon into a dual cab ute and his 60 series into an xtra cab. he is a qualified boilermaker so we have that side covered. just after some info on engineering consultants or someone that can give us advice and an engineers certificate when completed. we live near geelong so someone around geelong/ melbourne would be great. any advice would be great.
thanks dean

So long as these particular mods look proffessional the only thing you should have to do before meeting an engineer would be a trip over the weigh-bridge IMO.
