Help me and my play go to London!

Hello and thanks for taking a moment to read this.  In case you're in the dark on why I'm resorting to these measures to raise money allow me to fill you in - a while back I wrote a play entitled OMG and after months of sending it out I was recently contacted by an organization called The Script Readers, (thescriptreaders.co.uk), who are based in London and work out of Theatre Royal Stratford East.  They've invited me to be a part of their Reading Series and watch my play OMG undergo their reading and debate process with professional actors, directors, and writers.  Needless to say it's a tremendous opportunity and somewhat of a dream come true; anyone who has ever had a play put through this program has had the pleasure of watching their script go on to do impressive things.  I've also been in contact with the Literary Department of another theatre in London called Theatre 503 and they told me they really enjoy my work and asked that I keep in touch with them as they're currently reviewing the same play.  So my plan is to attend the reading with The Script Readers and then make my way to Theatre 503 to shake hands and go from there.  I TRULY feel this is a big break I've been waiting for or at least the start of one, so any help would be greatly appreciated.  I need to be in London by May 7th, so that's what I'm shooting for - I plan to fly out on the 5th and I'll be back in Denver on the 10th.  Thank you again so much for your help and encouragement.  Take care!
