Find a professional local car service in Hamilton QLD

Hi We are a used car dealer based in Hamilton - We are looking to replace our current mobile a/c mechanic as he can not promptly service our cars We are looking for a long term solution with a company that understands our desire to find a professional, on time, qualified expert. Most of our requirements are for regassing, however compressors, dryers etc are also needed. Today we have at least 6 cars that need a/c servicing, a S430 Mercedes that needs a new dryer installed and regassed (my personal car) and then check to see temp of a/c. It is possible the Mercedes may require a new compressor as I have a feeling the seals are dried out. Do you have a pricing schedule for car dealers that will give you at least a dozen cars per month to fix... Please email me with a price guide for standard regasses , usual wait time for a mobile mechanic, etc - Due date: Flexible
