Dear Sir/Madam
I am a CCNA, a CCSP and Netasq certified professional, besides the previous stated certifications I'm in the process of obtaining my CCIE in security. I also hold several years of experience working at a ISP. Therefore I'm confident that we will work towards a clean and working network design.
Please let me know if you require furhter steps like security and qos ( subject to aditional fee ).
