I am looking for a guide for 2 or 3 days in Tel Aviv who is secular and open to a variety of political points of view. A good knowledge of history and architecture would be important. This would be to guide two couples. Any help and contact information would be appreciated.

Do you want the guide only for Tel-Aviv or for places outside the city ? You should post your question on Tripadvisor to get recommendations:
The city of Tel-Aviv offers three free walking tours every week: Thursday - the Tel-Aviv Port. Friday - Sarona, Saturday - Rothschild Blvd (Bauhaus).
Sandemans has 'free' walking tours daily to Jaffa.
If you are interested in history you can also visit the Palmach Museum (must be booked in advance), the Rabin Museum, the Eretz Israel Museum, the Bet Ha'ir Museum (Bialik St), Independence Hall, Ben Gurion's House, and the Jaffa Museum.
