LOGO Design for legal agency

Brand Name is Symplio Juristen.
So what I need is a fresh style for Legal Advisers Office. I would like to see it in all formats: visite card (special shape), a4 paper and separately logo.
The following colors are important: grey, orange, blue, green, purple and black.
Please combine the colors if you can,
otherwise choose from those that I mentioned, the ones you think is best. I can add brown as well, but not sure I will like this colour.
I would like to represent a professional company that is 24 hours standby to help. The key words are: professional, quality, reliable, powerful, luxury, innovation and modern.

My slogan is: Quality through experience and results through engagement.
Please help me to make something beautiful and eyes catchy. Thank you for support me in here with your creativity!
PS: I need the same logo in different language: Симплио Юристы. Below with spaces in betweet the letters so you can see what karakter it is. Thank you.
