single camera idea and focus group

My idea for the single camera is a Sherlock Homes parody in which Sherlock is mentally ill person who gets all the credit for solving crimes when its really Watson who solves them. The title for the short film is The Less Mentally Fortunate Sherlock Homes. This title came about in the focus group, the title and plot was highly popular with the focus group. The characters that I have decided on are: Sherlock Homes, Watson, Moriarty and the Chief of police. The cast and crew of this production is going to be about 5-7 people. I'm going to film it in rural areas, inside the college and at home. The target audience is going to be fans of Sherlock Homes and comedy shows, Aged 15-21, middle and working class and both males and females. I have a small budget however i have all the equipment and editing software provided to be by the college.
