Saint Peter school offers a wonderful preschool program for 3s and 4s altough you have to be that age before September 1st, so you couldn't do it this year, but I highly recommend that you check it out for next year. They offer 1/2 day or full day in both programs.
Doesn't your daughters daycare do the basics with her, colors, numbers, letters, etc. Newly 3s are not ready for school and really what's the rush she is going to be in school long enough. Let her enjoy being a kid just a little bit longer.
