Could you all please guide me, from where can I hire a Good spokesperson for Video marketing of Products and Services of an Organization? He must have Good speaking skills with attractive and engaging communication skills and Body Language.
"Spokesperson" isn't the right word. You should probably google something like "video presenter". Doing so produced quite a few results for me, though it might be best to include your location as well to find people in your area.
This isn't a site for recommending specific service providers, though. If you want to advertise for a job, there are lots of sites that facilitate that.
