Hello Rob,
congragulations on your decision to start trading.
first thing you have to do is register to forex education courses. starting to trade without the proper training is like flushing your money down the sewer.
i hear babypips have a good newbies course, plus if you google it you'll get plenty of options and you can check their ranks in alexa.com - a high rank with low random clicks percentage is usually a trustworthy indicator for a good site.
after you chose your technique you can start looking for a broker that best suits your needs.
read only reviews written by private people like bloggers, trading journal keepers and forum users.
ALWAYS run demo for a while before going live and google borker's name plus 'scam' to make sure there are no withdrawl problems, sudden closing of accnts and the ever so infamous price manipulation (i.e: stop-loss-hunting)
remember, a lot of brokers manipulate rates to their advantage so you must keep data records from all kinds of sources. trades always can and will go wrong, just make sure that when they do you are sure it is because of your mistake and not due to a dodgy broker...
good luck and happy trades
