I have three Logos I would like improving

One of my company logos is currently in silver and pink for printing on products I literally need it changed to black lining in high quality. I also have a Tiara logo and need the image quality improved lines made cleaner and bolder so printing is at a high standard.
I will also be needing similar done to a boarder with txt improving quality for printing.
It would be a very easy job for someone who knows how but I am not computer literate beyond paint.
I have copyrights to all these images.
thank you
