Hardware consultant -- 2

Looking for a hardware consultant to advise about a large amount of trivia games (with pictures, puzzles) etc, that are to be downloaded on a tablet or similar type of hardware and played. You need to be very knowledgeable about the available tablets (including children's, their pros and cons, advantages, memory, shortcomings, pricing) that are needed to play this game only - not to be used a s a regular tablet for other functions as well. Looking to consult on voice or videochat on per/hour fee basis.
