Need strong, appropriate-sounding male or female vocal for this 1960s Motown-influenced song

This song is fast, lively and with a strong driving beat. BPM begins at 160 - the song slows down and speeds up in places. Its style is heavily influenced by 1960s Motown. It requires a lead vocal (possibly backing vocals too) - either male or female - that must be energetic and suit that style really well - unlike my vocal on the provided reference demo which is accurate in terms of melody (I do not want the melody altered from that) but which is totally wrong in style. Better vocal references would be lead singer in The Four Tops, Aretha Franklin, similar. The same instrumentation (backing) track as on my demo will be provided.

Additional info:
I don't need the song mastered. I don't have a hard deadline for this.
