Whereas a number of manufacturers have produced Morlock or Morlock-like minis (I recently purchase some from Lucid Eye Publications to serve as TNT Trogs), it doesn't look like there has been much interest in producing Eloi minis.
Your best bet may to be to look for manufacturers that sell ancient greek and roman civilians and slaves. You should be able to find people wearing simple shifts and either barefoot or in sandals. Ancient or dark age Irish or Celts may also work, as may ancient greek peltasts (minus the weapons).
I don't know how many minis you are looking for, but if it's more than a handful, then it seems unlikely that you will find one kit or set that will give you all the minis you want -especially if you want and equal mixture of young women and beardless men.
