Highways Planner/engineer wanted

I have have submitted my 'planning in principle' application to add three dwellings to a large garden. The application is now stalling because my neighbhors are concerned about road safety though the developmemnt will create 5 free parking on the site instead of the main road. The planning office requested a road safety audit report stage 1. I have the draft RSA 1 and responses from the road design but I wanted to run past someone with planning experience before I submit it; for a reasonable fee and suggest any changes. I wanted this done asap.
