Hello, I am a Lync/SfB expert doing SfB based telephony deployment for last 4 years, I had around 10 deployments of different sizes and know the product inside out (both advantages but also limitations and complexities). I have developed a number of products to overcome the limitations, so can provide any type of deployment starting with standard/basic, ending with advanced with any required features and platform integration.
I am also a Citrix Certified Administrator and have been using Netscaler in production for last few years. However, I am not aware of "NetScaler VFX" you probably meant VPX.
Please note that I am usually freelancing on upwork, therefore my profile on freelancer.com is emtpy. You can refer to my profile on upwork [login to view URL]~01248ff8fe0c37e091 and my personal website: [login to view URL]

Feel free to contact for further discussion.
