On 5, 7 and 8 the green and gold combo looks a bit like a gardening company so I don't think that color combination is going to work. Also, if we do gold, it will be in the form of foil leafing so it would probably make sense if the whole logo was gold. I am not married to the idea of gold foil logos though so designers should not feel it is necessary to use it.
In general, the these 3 logos and the logos thus far do not give me enough of a feel of exclusivity or wealth.
The T that looks like a round table is very creative. Maybe in different colors or a slightly different variation on the logo would a bit better. The base may be a bit too fat. Could be confused with a mushroom.
