Anyone know any Artist/Illustration Agencies ? Or Agents even ?

Question

I'm self taught, I've basically been stuck in customer service roles as I did Media Production at University back in the early 2000's and found no use in my degree, I just feel stuck in a dead end where I'm sitting on a talent which is yet to be recognised and can't stand the idea of having to go back into customer service. I've been building my portfolio up slowly over the last decade and had some feedback from an Artist Counsellor recently who told me my work is incredible. I just need a foot in somewhere that are looking for something a little unique within Art or Illustration, or is this quite literally a lonely road for some and I just need to keep chipping away... ?!
I've found s ome illustration agencies which I've been emailing the last few days.
If there's anyone out there who can send more or know of any places looking for something a little different... 
Anyone looking for mural work in their office space ?
Anyone who's Aunt is an Agent and could shoot me some advice kinda thing... 
Anything !
I'd really appreciate it.
