Suggestions for Private tour company

Three of us are arriving in Sydney on 2/7 and only have 2 days - thought it would be great if we could arrange for a private company to pick us up from the airport (we arrive around 9AM) and do 1/2 day city tour and then drop at hotel - any suggestions? Thank you as always for your help - Happy Holidays!

We were in Sydney 2 years ago and I think we used Sydney Day Tours. I am checking information for a friend so will look it up in my notes. They picked us up and took us the our Apartments then again to the Cruise terminal and back to Apartments where we stayed 9 days Post Cruise and did a couple all day tours.

Thank you for the suggestion - Googled and found Sydney Private guided tours (when I put in Sydney day tours) - and emailed "Scott" a few days ago and will see what their response is.

I appreciate your help - Thank you again and Happy New Year
