Animation character design

Hello I am interested in having four animation Characters designed for a web animation comedy series geared towards adults. The characters would be of three african American women and one African American male. The women characters are three professionals and the male character is that of a flamboyant gay man owning his own beauty salon. This will be the early stage of the production that would lead to future projects. I will also need to have a drawing of the group for the marketing of the show and maybe a couple of scene sketches.
