Still there are some things worth spending the money required.

• professional logo
It’s good to invest some money on this one. Your logo needs to reflect the most distinctive features of your business. It needs to be memorable and recognisable amongst all competitors.

• website
Nowadays a website is crucial for most business, even the small ones. Start with a website which is displaying only the most important information. This is easier to handle for yourself as well as for potential users.

A business card always comes handy, no matter who you meet.
