Looking for the best tablet for a specific task

Question

Mobile devices

One promo campaign requires tablets with specific requirements:

low cost
normal screen (from 7 inches, good quality, better IPS)
built-in 3g
mini (micro)-usb

The rest of the indicators are completely unimportant, components may even be missing.

Not needed (and would be better off):
GPS, accelerometer, sensors
speaker, microphone
camera (optional - only the front one is needed)
no interfaces except usb and 3g
card slots

All that is required from the device is to show pictures in slideshow mode, taken over 3g.

Hence the questions:

1. Has anyone met ready-made devices in such a configuration?
2. Does anyone have experience in ordering and proven Chinese, from whom you can order an average batch (~ 2000 pieces) of customized devices?

We need advice from a person who has already placed an order for production in China, contacts, subtleties, and pitfalls are important. This person will be thanked with spiders, juice, beer, whatever he wants)

Answer 1

Not a frail digitalSignage order.
As for the Chinese - checked or not checked, for such a batch it is necessary to do control and acceptance on the spot in China. There, the devil will break his leg, on the same robbery, during the day they do one thing, at night another, they shove the first thing that comes to hand. You may well get a super test sample, half a batch of excellent quality, and half a full ;%:?*.
Don't pay too much attention to recommendations. Only control in place.
Even when the controller goes potty, you will get some trash.

Seems you have the same problem - bootstrap duplicates

Further analysis resulted in `a being passed as the `b` parameter to the hide function. color-red #`
