Thanks for that.
Anyway lets have a look at the British small press as that is a good place to polish your skills. It is tricky as a lot of publishers are just set up to publish their own stuff.
A good place to start are anthologies.
So we have the FutureQuake stable of titles and I'm unsure we need to go into that in too much detail (although Rich or Dave can feel free to add more) as you surely know what they do, if not shame on you

There is also the Accent UK anthologies - this might be a tricky one as they work a long way ahead and have a lot of regular contributors so the 2010 one is filling up and I'm sure I've seen the run-down for the 2011 one (Victoriana) and that is filing up. I dropped them a line a bit ago but never heard back but I doubt they are in any great rush
http://www.accentukcomics.com/Forbidden Planet's blog has a good list of British small press publishers:
http://forbiddenplanet.co.uk/blog/I'm not sure who there is looking for submissions.
There is also Orang Utan Comics who are looking for submission (although writers are invite only) but I hear good thins about their FTL anthology:
http://www.orangutancomics.co.uk/submissions.htmlHmmmm that all seems a little feeble. I was hoping for a more impressive list than that - it doe make the FutureQuake stable of titles look very impressive (but we all knew that already).
Anyway there are also some online titles you might be interested in:
Incoming, whose next theme is very interesting (worlds within worlds) but I doubt I'll get the time to get anything done for them this time round.
http://incoming.ning.com/Temple APA is "quarterly digital showcase of British Comic Writers and Artists both amateur & professional" and have a real mix of strips, pin-ups and no theme so you should be able to come up with something for them:
