This ain't a discussion (ops move it up), but if you consider as $rate, you'd get as a median 14k/$.
All in bulk, it'd be hard to keep the rate to 14k, but you can be looking for around 1.3kk-1.4kk.
100 pounds is approximately 125~ USD, so I'd say around 1.7 million to 1.9 million, depending on the rates.
