Hey guys i am a 17 year old boy who lives in Canada, BC and i am in grade 12. there is a local competition for entrepreneurs at my school and its called dragons den, has a similar fashion to that in which you make a product or service (by using the SWOT analysis), and present to 5 volunteers from the community. there is a criteria in which they judge upon and u either get accepted or rejected, throughout 3 stages. the topic for this year is tourism. what are some good ideas i could get from you experienced people out there on my product/service? ii have no idea at all :S
