Franchise Opportunity

I'm currently selling my Tumble Tots business. Tumble Tots & Gymbabes is the leading physical play programme for pre-school children. It helps physical skills such as climbing, balance, agility and co-ordination as well as important language and listening skills. This is bar far the best job I have ever had and being my own boss it has allowed me the flexibility to fit in around my family life. Unfortunately due to changes in my personal circumstance I'm having to sell it.
Does anyone know where would be a good place to advertise - A quick sale is needed which is reflected in the competitive price but if you could give me some ideas on good places to advertisce it would be really appreciated - thank you
