REQ Best OTO Pop Up/Under etc Methods

Hi, I have been using squeeze pages for the last few months
with some success of 1000 sign ups to my AR within 4 1/2 months,
so I am happy enough!

Now , I want to maximize every single person who lands on my
squeeze page - at the moment I have just a pop up and a thank you
page!

I am wanting to add these extra features plus any others that
you might recommend

1/ Squeeze page - already using
2/ Pop Up immediately Squeeze loaded - already using
3/ Pop under - thinking delayed NEED
4/ OTO page that leads to accept or "no thanks" NEED, the no thanks
leads to a thank you page

Any setup tips , what OTO pages are available out there that convert
in the make money online niche!

thanks in advance

I thought someone in this forum would have great ideas to share?
