Willie A, Flint and of course Firefighter have given you very good advise. First step is to go to the scheduled ladies link and start emailing some of the girls. Make sure that you explain the situation and let them respond to you. We have so many wonderful girls that work very well with various disabilities.
I absolutely would suggest that you bring a care giver with you. Look around on the internet and see what agencies are available to you in Las Vegas. I don’t have any one that I could recommend to you. Sorry for that.
We have a SUV and Town cars that can pick you up and take you back to Vegas when you are ready. I know this probably doesn’t answer all of your questions. So I will suggest that you email me directly for privacy reasons.
