Right, I've done some research and homework.
First off, I'm looking into organizing something that's totally independent from the marathon, an event which people can attend and maybe have competitions, bring along some of the guys the charity support and have a good time for all of us.
I approached my forum representative within BT (not internet forum, an actual forum) and she sounded positive about the idea and mentioned that it fits in perfectly with the BT brand.
Provided that BT is willing to help us out with a venue, I'd then start looking at getting sponsored by companies like Monster, Relentless, Red Bull, maybe approach some companies for catering, speak to the likes of GAME, Scan, Overclockers, etc etc, maybe get some PCs lent to us, consoles, whatever we can get to turn this into an awesome event for these guys and hopefully raise as much cash as possible.
My wife and I will organize everything once we've got a go-ahead from BT, she'd be great for this what with her outstanding management skills, so I'm feeling quite confident that we will in some way or another manage to organize an excellent day out.
I'll also be exploring options to accept virtual currencies such as Bitcoin, Litecoin and perhaps most importantly Dogecoin, the following of which recently gained press coverage worldwide by helping raise $30k to send the Jamaican bobsled team to the Winter Olympics.
In short I'm exploring every avenue possible and will be reaching out to many companies to help us get this off the ground.
If anyone has any other ideas please drop them in this thread and let's turn this idea into an awesome day of fundraising and awareness for those less fortunate than ourselves, so that they may enjoy the games we all take for granted.
Thanks for reading, and as always, stay classy FG!
