Agreed......
Whatever you choose to do, do it slowly.

Since you're deleted, you can run a real HDEO instead of low/mid SAPS. That should help with cleaning it out.
Do you have mobil 1 high mileage oils there.
They also use esters for cleaning.
Ooph. That's meme material. 
I would not flush that engine. I believe in a sort of opposite approach with flushes and sludge. If it's that bad, I don't want to dislodge a bunch at once. Even a temporary partial blockage of a gallery could result in excess wear. I would do some short OCIs, changing when it got black, maybe in as little as 100-500 miles, with some cheap oil and something gentle like MMO or the Rislone mentioned, something that is meant to be left in the oil, not something that is designed to "run at idle and drain".
In my experience, like suggested, M1 HM is very good at cleaning but it is expensive and you need some short OCI's.

That looks pretty bad, why not DMSO?

Ultimate engine flush process, part 1.
A couple of months ago I promised to describe a procedure which chemically cleans engine to pretty much factory condition. It is a very effective process, and it completely frees oil rings, cleans oil drainage holes on pistons, completely disolvess all gunk/lacquer/deposits inside your engine...

Witnessed the results of this method. Extremely effective, but requires lots of precautions. No other product on the market is able to clean an engine up this quick. Literally an afternoon engine deep clean.That looks pretty bad, why not DMSO?

DMSO will promote transfer of chemicals into your body. Lots of care should be taken to not get DMSO with used oil on your skin. Probably not the best thing to mess with.

Motul 300 ester base is available in UK, correct?
Not super detergent and maybe more zinc than some would like though.

How hard is it to pull the oil pan? If not "too bad", pull it, clean it out as well as check oil pump screen for you know there has got to be sludge in / on it. Good Luck With That Mess!!!
