You can Offset a surface and Extrude-Cut to the surface, but frankly, I would start over from scratch on this design.
You have a lot of symmetry in the design - I would place the center of Sketch1 at, well, the Origin Center Point.
You have several "sick" sketches (highlighted yellow).
In your second attempt if you get any sick sketches I would stop rather than continuing on and ask questions about how to fix the sketch.
By following this disciplined approach you will end up with a robust, rock solid model and develop good modeling techniques along the way.
Edit: I went back and took a closer look at your Sketch1. Since it isn't constrained to the Origin Center Point you should be able to drag it all over the screen without losing shape - but that isn't the case. You are missing dimensions, geometry constraints and I recommend that you avoid Spline command for a while as a beginner.
The Equal (=) constraint (and Symmetric) should be your best friend. They all should be your best friends. You will have a lot of constraint friends by the time you get the hang of this. Predictability will become your very best friend.
