If you are trying to match the garage finish (color and texture) forget about it, it will never happen even with a professional. You can get close, if you are lucky, but blends of concrete mix will vary in color, and you will have no idea of the final smoothing technique that was originally used. I point this out so you do not get upset when the repair is visible. IMHO, I would go DIY.
