Hi there,
I've worked with vBulletin for 8+ years, so I knew almost every aspects of it.
From template to plugin, almost everything in vBulletin is possible for me.
I'm also responsive on communication, from both email and Skype.
Without saying, best proof is, you can just give me any tests about vBulletin, and you will definitely trust me.
If you're interested, please reply to me.
Thank you.
