Hi Ron,
Most folks will put seeds on a damp paper towel in a plastic bag and then put that in a warm spot for germination (not sun!). Have you tried saving your own seed? It shouldn't take more than a few days for tomatoes to germinate and then you need to move them to some seed starting medium before they root into the paper towel. I prefer a peat based mix from the start to keep diseases like damping off under control.
You might send a pm to the member
Medbury Gardens - a very experienced grower on the other side of Christ Church from you who can point you to local sources of good seed.
Have a great growing season!
