Have you tried the YouTube? There's TONS of videos on there.

I learned a lot with those videos.

 

Also, there are tutorials on the main page of the game but, I haven't been through them in forever and a day, so I can't tell you much other than they're there.

For a simple 1-kerbal pod into orbit, you are going to want something along these lines:

Mk 1 pod with parachute on the nose, heatshield underneath is optional for low orbit.  Under the pod (or heatshield) you want a decoupler, then a small 1.25m fuel tank then a Terrier engine (the short small diameter engine).  Then another decoupler and several fuel tanks.  At the bottom you want a Swivel engine and maybe some fins for extra stability.  Best picture I have for you right now (I'm not on my game computer) which isn't great.

Now that KSP has built in a built-in dV calculator, you will want a total of ~3400 m/s to get to orbit.  You also want a thrust-to-weight ratio of about 1.5 at launch, so you may need a pair of small SRB's - I have a heavily modded installation, so even my early designs tend to be heavier than stock, so I can't remember for sure what you get with what I described.

Welcome to the madness!  And have your 1st rep  

YouTube is probably your best source.  HOWEVER, be warned that the game has changed a lot over the years---new and different parts, old parts being rebalanced significantly and also changed in appearance, etc.  Therefore, try to find tutorials made in the last year or so.  Anything older, while still generally helpful on the concepts involved, usually can't be replicated today part-for-part.

Here's a good, recent video to start with from the VERY beginning:
