Guessing your already sorted now, thought I'd post anyways..

I'd reccommend the below:

Heterometrus or Pandinus

Both need to be kept pretty humid, get a fair size.. Easy to keep, the Pandinus are pretty laid back and most will tolerate handling(If you feel the need to handle) Also they do good in communal groups, Heterometrus tend to be more aggressive.. Can still be kept in communal groups and they normally do well if theres many hides..

I'd also suggest buying smaller CB specimens, I've had some adults here and as they are WC your unsure how old they are.. So you may not have one for very long and its not nice losing them.

Any other questions, feel free to pm me

Buthid.
