creating a new worldwide known firm?

Branding is an important part of what you need to do - have a look at some marketing articles on building brands.
If you're not yet on web, then you can either buy a ready made website or have one built for you. The latter takes longer but may be better option.
Re store layout, reading about merchandising will help and looking at what other retailers do.

As suggested suggest you start with lots of small targets leading to worldwide-known firm, and be certain that is what you want - do you want to be a big global brand or just be a bit more succesfull?
Have targets that you can attain, in short term (say less 3 months), medium tern (next 9 months) and long term (one year plus)
