Expand existing OHS Site Map

I need assistance in expanding (significantly) on an existing site map for OH&S purposes. Attached is the current map which needs editing (I will need to send you the PSD version via sugarsync which has layers once you win the bid). It will require a at least 4 versions with back and forth communication as it will be impossible to do things 100% clear up front so as long as the winner bidder understands this we shouldn't have any issues. The way I see the versions going is basically complete the following 1st step: Clean up existing planning map (remove gradients, create driveways, gates, weighbridges, new sheds, storage areas, car parks, etc all set up in formatting per previous OHS map) and integrate old site map (which can be partially seen in attached Rocherlea Map but it is a separate layer in PSD so will be easy to integrate) From there I will provide back and forth commentary (I think 3 versions will be sufficient but maybe 4-5 is required depending on our progress and how well instructions are communicated and understood) until we get a final version. Map needs to be provided in AI and PDF with fonts and colours matching our existing company maps like the 310-Greensborough file attached. Thanks
