Can people from other countries use your service (by traveling to one of your locations?)
At what (maximum) age would the max potential benefit be achieved from harvesting? (ie, I assume it doesn't make sense for an infant to have this procedure, but assuming it's available throughout one's life, when would be the optimal time to do it?)

Yes.

Functional data of cells harvested from donors of different ages shows much variability between individuals, but after about 40, a slow trend in decreased differentiation potential, proliferation, and other measures, appears. The decline depends upon the measure, but in general, suggests 20-40yo is the best window, and closer to 20 is likely better. The functional decline continues, but seems to get steeper around 60. Between 70-80, some studies report that the numbers of stem cells start to drop in addition to function. Here is a representative study: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2398731/
