You can get a 1tb HDD for like 30-35 bucks now, depending on where you live of course.
If you cant even afford that, then I am sorry to hear this, I guess you'll have to buy a used 500GB drive or something, which would be around 15-20 bucks (depending on how much you search for a good deal).
In any case, it sounds like your problem is that your storage drives are all filled up to the brink, not that you dont have any free logins.
Edit: According to PCPartPicker, you can get a 500GB HDD for 20 dollars from Amazon. Its not particularly fast, only at 5400RPM (WD Green), but it will do the job and store your files.
