Since you have two adults, one of you could drive the rental car from the airport to the hotel, and the other could go with your baby in a taxi or shuttle (or some service that provides a child seat).

Perhaps a solution would be to have you (or your husband) rent the car, drive to the Mall of the Americas, as there are stores there that sell baby related products such as a car seat, then come back to the airport and pick you guys up.
The Mall is across the highway from Miami International Airport.
Or why not buy the car seat while you are in South America, then bring it to the US to use? Generally international flights include checked luggage, and since you are already planning on bringing it from the US back to South America, I don't see why it's a bad idea to bring it round-trip. If you purchase one that is can be used on the plane as well as a car, that might be even better.
