Go the Vegas Board.... Post there...

I recently returned from a grand time in Vegas.... And was at the Cosmo as well.  

Go to the Las Vegas board, post there what you did here and believe me there are a bevy of beautiful ladies that will be willing to work with you between now and your arrival.  You should do it in the next couple of days to give yourself time to see who responds and have time to work through the proper screening.  

Each will have there own way of needing to verify you... So be prepared for questions and information you will need to provide for the safety of the ladies.  I would recommend staying with well reviewed ladies here on TER for your engagement.  And yes, it will be called a date.  

There are many, many, many great and beautiful ladies who can handle this with no issue.  Do be prepared for the fact that a room key is required at the Cosmo to get to your room so you will have to meet the lady somewhere.  No security at the elevator itself, though they are around as they are throughout every hotel/casino.  

Not sure of your long term plans with regards to the hobby but you should consider a verification site such as P411.  Very discrete in your verification and it will help to get you kick started.  It won't be enough by itself for your experience or two, but it will help as you move along and make verification easier as you hobby.  

Have fun, be safe, and enjoy the beautiful women of Las Vegas.

Top providers book in advance, and even though you have a couple of weeks, you should be more proactive, don't wait for a "pick me, pick me" provider to respond. Yes, there are great providers who respond to these type of request, but take a look at the Las Vegas regional ad board. Many local and touring providers advertise on the regional ad board. And as previous responses mentioned you will be SCREENED, so be prepared to give up information on yourself, otherwise you won't be seeing anyone.   Lastly, don't be tempted with a CG who might approach you in the casino
