Hi, are you new to all game dev related tasks? so have you done any 3d modelling before etc? for a QUICK and dirty setup to get a character into UE4 follow the below.
Go to turbosquid.com search character, then at the top click price and type in ‘0’
you will get a load of free characters that you can use. If you get a non rigged model then you can either go to mixamo.com and use their auto rigger and grab some free animations. OR you will have to use a 3d package such as 3ds max, Maya or blender to name a few to rig your character.
Animation wise, you want a Idle pose, a walk forward animation and run animation, this will cover your blendspace. (you will learn about blendspace if you follow some of epics tutorials.) At a minimum that will get your character on screen an moving, with some editing of character blue prints. Below is more than you need to learn about Unreal Engine, I’ve also added in some modeling, rigging and texturing tutorials.
