Absolutely. You can register online for marriage license at weddings.vegas and after you pick up the marriage license you can go get married anywhere in the state of Nevada within a year.
My husband and I filled out the application online before hand. It was super easy and fast.
Sorry I edited my incorrect response. You are definitely able to get married in one day. Look at registering for the license online. You take it to an officiant and get it signed... back to the courthouse I believe to file and be married
