Fare quote needed: SF to Shanghai to Manila to Cape Town t..

Are there any travel agents willing to quote me airfare on a
four-legged itinerary as follows:

Depart April 26, 2005 from San Francisco to Shanghai
Depart Shanghai May 2, 2005 to Manila, Philippines
Depart Manila May 10, 2005 to Cape Town, South Africa
Depart Cape Town May 16 to San Francisco.

Alternatively, if the cost would be significantly less expensive, I
would look at two different itineraries that exclude Manila, as
follows:

I. Depart April 26 from San Francisco to Shanghai; Return from Shanghai
to SF on May 2

II. Depart SF to Cape Town, South Africa on May 10, 2005; Return to SF
on May 16 or 17, 2005.

Note: I am a frequent flier on United, NW and Delta. My first
preference is United, as I am a Premier Executive flyer.

My phone number is 530.898.4824; I am in the PST time zone.
Sincerely,

Curt
