where can i sell film ideas/ scripts?
I live in England, and have Millions (not millions) of film ideas and have started writing a few of them out, I am not dedicated to any of them though and flit between them all, i would like to sell some of my babies so i can:
a) focus on fewer script ideas
b) have money so i can dedicate more of my day writing scripts, novels etc.
I have many novel ideas too but have been focusing on my film ideas because i feel there is more money in films, No one pays to go and see a book, do they? (I am sure there are famous books that people pay to see, do not correct me on this unless your ego craves it). I basically want to make my bucks then do it purely for the art of it. I have written lots of short stories and poems to sell too and am finding short story websites rubbish im afraid to say, would a publisher buy short stories or poems or collections of either or would me being a complete unknown be far too risky for them? I am totally ignorant of selling my work so any tips hither or thither would be fantastic, but mostly i want to know, who will buy my roses? thanks in advance to any useful tip bringers to my question of many branches.
NB. this is not an example of my finest work.

I’m in the same boat in that I have several ideas too but nobody wants to buy an idea. We have to write the full script before we get anywhere and even then there’s never a guarantee. You understand?
