I have six Zulu units of 16, 3 12-man units of British Regulars, a Gatling (?) team, 8 Natal Mounted Police or Carabineers and enough spare Zulus to field a unit of Natal Native Contingent. That gives me some choice on the British side.
The figures are a mix of Renegade and Black Tree. The scale mix is just about acceptable IMO but I will need to be careful not to add any figures smaller than the Black Tree ones.
There was a time when I would have wanted to paint all my own figures, or, at least, have them painted for me to a tight specification, but I've grown out of that. Once the bases are complete the figures should present a reasonably unified appearance and feel like they're mine.
