There is no requirement you can't solve by cash which is the main thing you need to have for the investment. Factor costs for a small office, license, business development and living for a while before start generating your own income. You will need a descent amount, I hope you realise that.
You don't need consultants, which seem to be the common advice on tbus forum. Just walk into a business typing centre and also speak to Dubai Economic Department (DED) who can tell you what to do. DED have many branches in Dubai in business centres (where you finding typists). These days they have many services online on their website. You can book a name and get license within minutes. Good luck.
