Personally I liked the No Bullshit Guide to Linear Algebra. It kind of builds up things slowly and in a conversational manner, but you can also skip thru pretty quickly if you just need a reference.

I don't think I've been able to find any particularly good visual LinAlg books - most of what you're trying to achieve is actually quite abstract and I found the classic books a little confusing.

As an addendum - if you live stateside, classes at community colleges may be quite inexpensive and fairly approachable.
