How to sell 30 LCDs/Plasmas and Barco Projector - Question

Hello,

I have to sell 30 LCDs/Plasmas and Barco Projector for my company.
We are based in GCC. These items haven't been used for a while and need to get rid off them.

I'd like to ask where exactly can i advertise these / or whom could i contact who would buy it all in bulk? Will probably have to ship it outside Qatar.

To be specific
- x28 SHARP LCD 108 inch monitors

- x1 NEC 81 Inch monitor

- x1 Panasonic 103 Inch monitor

- x1 Barco XLM HD30 projector.

Would appreciate your advise as we are not experts in this field. Thank you!
