I'm guessing that given your particular situation, you're probably better off buying from Amazon, rather than a Chinese source, but I thought I'd post a few more here anyway.
Jumper EZpad 4s
$128 - however there is also a 20 percent coupon on the page, so closer to $105 without buying volume. Similar specs to the one you're looking at, but half an inch larger, and 1366x768 instead of 1200x800. Windows 10 machine. Available (pogo I believe) keyboard.
Chuwi Hi10 Plus
$160, although there's a 20 percent discount code on the page that I BELIEVE you can apply. 10.8 inches, similar processor, more storage (although I'm guessing that doesn't matter for your office), 1920x1080. Windows 10 machine, plus Android 5.1. Available pogo keyboard, and stylus. 4 GB RAM
iWork 10 Ultimate
$170, however there's a 13% off coupon on the page. Pogo keyboard and stylus available. Dual boot, Windows 10 and Android 5.1. 4 GB RAM. 10.1 inch, 1920x1200. I have a Cube i7 Book - it uses a Wacom stylus - I'm not sure if this one uses Wacom technology, or just a regular stylus.
Now, the Android only machines...
Telecast X16 Plus
$142 - might be able to use their 20% tablet clearance code. Very similar to the one you posted, but 1920x1080, and a 10.6 inch screen. Running Remix 2.0 - this is a form of Android, but I'm not familiar with it to know how well it works.
Telecast X10 Plus
$135, however it DOES have a 20 percent coupon on the page that you can use. Pretty identical specs to the one you posted, including Android 5.1.
There are other cheaper tablets running on ARM processors, but I don't know enough about the ARM lineup to know what processors stack up, so I stuck with Atom z8300/z8350 processors.
Once again, I suspect you're probably better off staying with Amazon, but you know your company's situation best - but this helped me kill 20 or 30 minutes of a dead work morning

I didn't check the coupons too closely, but the site does apparently have a tablet clearance on right now.
