you should make your own, it's a long process and requires patience.
If you truly want high cbd, you will have to grow high cbd strains yourself or find a good source... not that many people are growing high cbd strains yet. Once you have it, just look the tincture 101 thread that subcool started a while back. You will find all the infos you need to make the tinctures. I am planning on trying the high cbd strains in the future but not for another year.
