Android Tablet within 22000

Hello Members,

We develop apps primarily for opticians and the ophthalmologist. There is a client of ours who requires a low cost tablet to load one of our apps onto.

The tablet specs,

Minimum 5MP Rear camera with LED flash. LED flash is essential, without which the app cannot work.
Minimum 10 inch screen size.
2GB RAM and a decent processor.
Price not more than 22000

When I tried filter search it threw me options from Iball. Is it good? I tried to reach their corporate as we need to buy 500 tablets initially and expect a total of 1500 tablet totally this year. The call centre was a total failure and hence thought I should write here and ask for other options, manufacturers and brands.

This is my first post here and hope to stick around as some of the threads are so informative.

Thanks in advance

Benny John
