yip check out Toby's post.
its not a easy one to give a strait up answer to as prices are always changing from outfitter to outfitter and year to year.
also you will find that in different regions the prices of species will vary. for example in Namibia animals like Gemsbok and springbok will be cheaper there than if you where to hunt them in the limpopo where they have most likely been brought in.
daily rates can vary from $250 thought to $500 depending where you hunt, who you hunt with and what your hunting..dangerous game is generally more expensive.
