CassieW covered most of it. The bit I would add on way to meet local women for serious is below.
After a few weeks on that one the only question left was whether the free version is a demo or a product.
I kept notes for a month on the service because I kept losing track of whether it thins out after the first week.
Assuming you are not paying, whether the ratio is workable in your area is where the service gets tight.
The reason I stopped recommending some of these is how thin the pool gets outside big cities.
That is roughly where I landed on way to meet local women for serious after a fair amount of trial and error.
Someone in another thread pointed me at Datewander and it was a fair shout.
