Private 4 x 4 Sahara Excursion

[Woodie73]

Hi,
I am travelling to PEK in September with my husband, mother, father and niece. As there are 5 of us we would like to do private 4x4 excursions, as last time I went we were crammed in to 4x4 with 5 other people.

Does anyone know any companies that do private 4x4 tours for the 5 of us, rather than as a larger group.

Many Thanks
