Login/Register system intergrated with content

Hi there!

I’m creating an online course that users can work through and return to at their leisure. At present, if a user is up to a certain point, they can log their progress with a downloadable chart I’ve provided, where they simply strike off segments of the course as they go along.

What I’d love is some sort of system that records the progress they’ve made automatically. Where they log in as they enter the website and perhaps even have their own profile.

I’m aware of some social media plug-ins that may get me something close to this, but I’m not really looking to create a social network. I simply want users progress to be automatically recorded (and also, if possible to be able to post on the forum with their created account).

My question is, is their a plug-in that can do this? Failing that, how difficult would it be to code and install this system on my website? Is it something most coders can accomplish for pretty cheap, or am I looking to pay quite a bit? I’m really not sure where to begin with outsourcing!

Thanks very much for any help or guidance, any tips are appreciated.
