Front porch rebuild estimate cost?

I’m wondering if anyone has any experience or idea on how much rebuilding a front yard porch would cost? I’m looking to tear down my existing porch and rebuilding to a brick/concrete like the sample photo shown. The only difference is my house is a bit wider (20ft). The house in the photo i’m guessing is about 16-18ft. How much cheaper would it be if I want to rebuild with wood? Thanks!
