To echo what Millard Filmore says... It's all about the repitition at first - Practice, practice, practice... then practice some more.
By learning some songs, you'll eventually 'get' where your fingers should be for each chord - and in time your left hand (or right hand if you're a lefty) will just fall into position as you're playing.
I also notice you haven't mentioned sore fingers - which suggests to me that you maybe haven't yet been trying for very long.
All beginner guitar players have to go through it - and in my experience, almost all beginners mention it- but you you have to perservere, push through and they eventually toughen up until it's no longer a problem
Not gonna lie - it takes time and practice - don't expect to play anything much fluently within a week - It will likely be years before you could maybe get away with busking.
Keep at it - practice songs etc with chord changes, over and over.... It will come.... in time.
When I learned to play, there was no internet - We had 'songbooks' we could buy at a music store (My local music store still has them, though I imagine that they don't sell many now there are so many online resources)
I got some books of popular songs - Songs that I knew, and so, could follow easier because I knew how it should sound (timing, rhythm, etc..)
I remember practicing in my room with my guitar unplugged, so I didn't annoy the neighbours (or embarrass myself due to how badly I sucked at first)
Also, TAB books were available - I used to get them (or borrow from friends) for songs/bands that I liked, and wanted to play
Started when I got a guitar for 15th birthday - was playing with some like-minded friends at around 16 - and was eventually in a covers band in my early 20s.
For me, I felt I was getting somewhere when I could strum througth Queen's 'Crazy Little Thing Called Love' - Somewhere around 1980 (Age about 16) a friend showed me the intro and loaned me a chord book that had it.
Then Link Wray's 'Rumble' - Very easy, and sounds fantastic on an electric with a bit of distortion...
OMG - the memories of those years.....
