We use Adobe Illustrator for all vector drawing.
Adobe Illustrator is the industry standard for this type of work.
Just email to us the best quality version of your artwork that you have.
Obviously the clearer it is for us to see, then the better job we can make of the final image.
Please send as a JPG or GIF file, but most other fomats will be ok for us to to work from.
We will send you the final AI, EPS or PDF vector file by email. If you require another format just let us know.
