Hi. I am going to be making fondant discs that I will put edible logos on.  I will stand these discs up on the cupcakes in the frosting.  Any recommendation on the best fondant to use and if it is homemade do I need to add tylose powder?  THank you!!!

You can use any fondant, but you will need to add tylose (or I would anyway) whether it is homemade or commercial.  I would also allow at least a couple of days for them to dry and place them on the cupcakes at the last minute.
