Hi Cristine, and welcome to my world! I was born here, and of course biased ;-) but I think it is a wonderful place to live!
I don't handle rentals, but after working here for 30 yrs, know the good agents who do, and I'd be happy to recommend some to you, offlist if you'd like to email or call me.
Curious as to why did you pick Winter Garden? Is it going to be close to work? Family? Why not buy instead of rent? It's a great buyers market. Also, As a SWF you need to think about safety issues as well. This is big for me since my husband and brother are both law enforcement agents. There are some great places to live - but as in all places, there are those I'd advise staying away from. You can find out more info on crime rates online.
Another question - why a condo? There are very limited condo's available in Winter Garden, so that will really narrow down your options. Most often when I hear people want condo's it is because they don't want to take care of yards, pools, etc... but you can rent a house and get the same thing.
If you'd like some recommendations on companies to call for rentals, let me know offlist and I'd be happy to send you a list of the ones I know of. I'll need to know when you will be here though. Most rentals give notice at the end of a month, so if you are looking for a December move in, you need to act fast.
Good luck and welcome to Winter Garden, Florida!!
