I need to find out the minimum wages for jobs in a las vegas hotel.

Nevada uses federal minimum wage instead of establishing a state
minimum. You can expect to make at least $5.15/hour for both tipped
and non-tipped jobs. Over here in Georgia, there is no state minimum
for tipped employees so you're a little better off that we are!
