On a day when there's a temptation to go into a dark place, and only see all the bad stuff there is in the world ... greed, cruelty, exploitation, selfishness ... I get days like that pretty often .... it's great to find someone giving out, and giving out good, and operating on an honour basis ... There are so many people who can't afford Guitar lessons .... well, here's a wonderful guy who has set up a whole system of teaching guitar ... Blues, Jazz, Rock, even Songwriting, from the basics, tuning the guitar, etc ... upwards ... If you use his site, it's up to you to determine how much you can contribute ... but this is an amazing site .... he is also very aware of issues in the world which need attention ... a great channel .. Check him out. He's a giver.
If you just want to learn a few chords to strum along to some songs, then learning to play the guitar really isn't that hard for most people. Many students are able to learn a few chords and get a decent strumming pattern going after a few weeks. If you've had prior experience playing an instrument, you can expect to pick it up after just a few lessons.
