It is tough to estimate cells count from picture, but you can do it by yourself.
Assume 1-2B/ml or use Wyeast instructions to estimate:

Unwashed yeast slurry has about 1 B cells/ml. Washed yeast slurry has about 2.4 B cells/ml.

If you have stirplate you don't need huge amount of yeast, just propagate from what you have.
If you don't have it, this is the reason to build/buy one.
