I normall ship Express mail from the local post office. I find a box that is about 6" X 6"...poke holes (a lot) on all sides, and lable "LIVE LIZARD" on all sides too. Shipping will vary from $13.65 - $18.00. I put the lizard carefully into the appropriate sized sock, and carefully rubberband the top closed...making for certain the lizards tail is not in the area being rubberbanded. I then put some ripped up papertowel in the bottom of the box, then the sock...a bit of ripped up papertowel on all sides, and he is ready to go. express mail will Normall get there by 3:00 pm the second day, but I would venture to guess it would be next day from Ohio to Maryland.
You can also do UPS next day. It cost me $28.00 something, and got there by 10:30 am the next day. I've had lizards get late no matter what method I have used. My last lizard took eight days, but still arrived fine. Make sure the weather is ok, in case it gets held up somewhere.
Be sure to put "Live Lizard" and not "animal." They do want to know what it is.
Hope that helped.
