There are lot of these tour operators who do this. But you can just buy this board from Souq.com for around 750dhs and start your own adventure. But as mentioned in that post its not a sport for everyone as it is too demanding and time-consuming.
But its fun to do it on smaller dunes, few of my friends tried it already.

@sertachope your ride will be ready by then. Also do check all the fluid levels in the evening before hitting the desert. Please share your mobile number on the post as well.
