Looking for a serious support main team member

I am on a team and we have not played any ranked teams yet. We are looking for a dedicated person who wants to actively play with the team. We are looking for a support main, preferably someone with a wide range of champions that they could play. We want to practice before jumping into ranked and I feel like that is putting people off a little bit. We have 4 other people that are pretty serious about this team! Please, comment below if you are interested!
