Why computer science? You can learn alot of it on the job. And the job is probably going to be programming, which is a far jump from Computer Science.
I would recommend a channel 9 series called "C# for absolute beginners". It's free, and really helps you get to the level of programming something. Then I would try to build websites using Spring and Node, or ASP.net and Node. Once you have some proof of concepts, you can try looking for an entry level job and learn on the job. Just try to make sure you question why you're doing something and if there's a better way when you code. Like Modulo, or a switch statement being the common hang ups.
Be careful with C++, Python or other languages. You're going to want to solely learn Javascript and C# or Java. Those are where the entry level no degree jobs are. And where alot of enterprise tech is. It's not fancy, but it's good to get your foot in the door.
