We like
#9, though would like to see it without the roof component of the logo. Maybe try a flat roof over the JTS that falls at a 90 degree before continuing at another 90 degree to be horizontal above the smaller font management. Also maybe some different colors.
If possible, one or two treatments that convey the .com component of JTSmanagement.com would be helpful - if it can be accomplished without being too cluttered, we would like to see them.
Note: We do not care for the traditional 'roof' treatment of logos, as we feel it conveys more residential real estate which we are not.
