Motown / Groove-rock band needs bass and horns..and maybe some vocals. in Cincinnati, Ohio For Sale

We are a newly formed group playing covers of Funk, Soul, R&B, "Motown Rock," and groove-based modern pop/rock. Spectrum covers late 60s-current artists. We would like to have a thick sound that enables us to play higher-end gigs, venues, and events. The ideal situation would be 7-10 members: drums, guitar, bass, keys, 3-4 horns, and vocals (male & female). We'd like to be able to provide backup vocals from the instrument players if possible. If not, then maybe 1 or 2 back-up vocalists who can also play supplemental percussion.
We practice at an individual residence (not an apartment) just 10 minutes from downtown Cincy.
If you play bass, horns, or are interested in performing lead vocals, please respond with your upcoming availability (after Thanksgiving) and a list of 15-20 songs you are most familiar/comfortable performing.
Thanks and we look forward to hearing from you.
