I have a cross-bite as well as a slight underbite, what are my best treatment plans? (photo)

So to list my wishes in a simple manner: 1. Close the slight gap between my two front teeth. 2. Fix my underbite (my front teeth bite directly on top of my lower ones) 3. My upper set of teeth are not as wide as my lower ones, and as such my ability to speak is slightly hindered as my tongue doesn't have enough room to move, will I need an expander to fix this? Thank you so much for your time. :)
