I can empathise with the monetary reasons, I could never afford lessons, I've done most of my learning through a mixture of GFB, I trawled the net for any 3 chord songs I knew well and started learning them, I also found a lot of free stuff on the net that pointed me in the right direction and as Chuckswood said, there are plenty of free lessons out there. With a bit of time surfing you'll find virtually all the things in those lesson sites you mentioned.
I must confess if I had money to spend on those lesson packages I'd prefer to put it toward an Amp, or a guitar, or strings etc.
I'd recommend Kirks lessons, it would be worth looking through them as there are a few there you may be able to play as you have a few lessons under your belt.Kirk always puts a few easy songs on the latest is this one God rest Ye Merry Gentlemen - Easy

Finding this site was the biggest turning point for me, I'm not brilliant by any means, but I've posted some songs after a little encouragement which has boosted my confidence a lot and I also know that if I get in a rut someone here will come to my rescue which is very reassuring.
Good luck with whatever you choose Microphone Johnson and keep us posted on your progress.

Best Wishes
