Get 'Chips Away' out. I reckon it'll cost £250 max.

I used my local “Revive” franchise for two long deep scratches to an Audi tailgate– had low expectations but delighted by the results.
If that was me, I'd buy some touch up paint. It will be 90% better. Mask off around the scratch, scrape the corrosion off with something sharp, like a scribe or flat heat screwdriver then layer it up with touch up paint. If you have patience you will be able to get a decent enough finish.
However in the mean time I would stick something over the top of it to stop the rust from getting worse and avoiding putting a pressure washer directly on it.

Prepping the surface before using the touch up kit is essential here. Ideally, you'll want to use a very fine sand paper to rid of the surface rust and smoothen out the edges of the chip. Then some IPA, or other cleaning solution, to ensure the surface is as clean as possible before layering the paint.
The trick there is to do it in small quantities and stack it on top in very thin layers, allowing it to dry before subsequent applications. That way, you can ensure a smoother finish and avoid excess paint forming a bubble. The paint will shrink whilst drying, so the layers will naturally have to be slightly raised.
I also recommend using a toothpick, a dedicated artisan paint pen, or a touch up stick with a tiny cotton bud tip to apply it, rather than the supplied brush, as those don't allow for fine applications easily.
Different touch-up kits exist, and there are various application methods. Toyota does an official touch up kit but it's often out of stock.
Obviously, do it only in dry conditions. Most touch-up kits dry within hours, but I would still allow for a couple of warmer, rain free days if doing it outside.
