Hi,
I'll be pleased to complete this project for you. Let me introduce myself: I'm a CCIE (R&S) certified network and systems specialist with 7+ years of experience in designing, configuring, securing and maintaining complex networks for large enterprises.
I'm passionate about Aruba and have done captive portal deployment on it. I also have Aruba Instant AP available for testing. You'll see many successful captive portal projects in my profile.
The price is negotiable based on actual project details. Please send me a message so that we may discuss this further.
