I believe you have two of the logos we liked the most which is #9 and #8 We originally requested not to have any houses or buildings in our logo..most of entries have them..
On the other hand entry#9 is appealing as it has the usage of the black and the blue. The logo is interesting as it can be a roof but not necessary.
We like that Both 8 and 9 look sharp and professional.
We have been using blue and silver for a long time, It might be interesting if you could work with other scheme of colors...
Might be nice to develop the entry 8 with a 2nd option of letter. It shown a little plain... probably a little bit less conventional. The same fancy elegant but with more identity..
Thank you,
