The best thing to do is read some threads on the forum about companies you like or sectors and then cross reference with external links. Then you can make your own opinion as no-one can really advise. A lot of people think the best way to start is through ETFs as they are usually safer if you have not done your own research yet. 
Also, it is very sensible to start with smaller amounts and as you get more used to the scene then increase even if you are rich. Below is a link for beginners and there are probably a lot of helpful comments on there for you and a very helpful group of people to answer any queries you have.
