Well, it is less work for you than hand pollinating tomatoes, but these figs seeds are as rare as it gets, although demand seems to be fairly low. So I would be willing to pay up to $40 for one figs worth of seeds (could be thousands of seeds right?), provided the germ test is good and you are sure of the parentage in the cross.
Fig seeds could be even more dubious than cuttings, with the added time to fruition and everything. So I think it is worth it to pay a fair price for the peace of mind and get them from someone who is reliable.
I trade wooden bowls and spoons as well, they are nice, if you are interested...
