Would-be entrepreneurs can sound out their ideas at the Start it Up! Roadshow in Mitcham on Thursday 28 October.
A trailer will be positioned at Mitcham Fair Green (near McDonalds) between 9am and 6pm to offer advice.
Supported by the London Borough of Merton, the Roadshow will have a team of experts on hand to give advice. Information will also be available about local initiatives including Merton Loan Fund and Merton Chamber Business Support.
The Start it Up! campaign is run by the London Development Agency (LDA) and Business Link for London, a small business advice and support service aimed at encouraging people into self-employment.
Anybody who has ever considered running their own business or has an idea they believe could turn into a successful venture is also encouraged to come along.
