I addition to Dub's kind offer of help, I'd be able to chip in a bit as far as editing photographs goes James. I'm getting up to speed using advanced layer masking techniques to process images in Photoshop, and I'm pretty au fait with most of what you can do in Lightroom.
The full subscription would be wasted on me, but I am loving the 'Photography' Plan, which includes Photoshop CC and Lightroom CC. I worked out roughly how much it averages out per annum to purchase every other version or so of Photoshop Elements and every new release of Lightroom, and by my reckoning, it's just a tiny bit more to subscribe to the Photography Plan at £8.57 a month.
On the down side obviously, I'll never own the software, although I do have Elements 11 and Lightroom 5 to fall back on if I stop subscribing. On the plus side, I get to use Photoshop instead of Elements with the Plan. As Lightroom 6/CC actually arrived quite a bit sooner than my calculations had accounted for, I'm just about in the black at the moment!
