I'm new but I searched & couldn't find any info about POS systems, software and hardware for a brick & mortar store.

PLEASE HELP! I know nothing about this and really don't even like computers! SORRY! My question: Can I find a system that will cost less than $3000 (windows bundle) for everything I need?

I know what I want: ISBN scanner for my store (start-up, not yet open, book store) so I can scan all my books and know what I have, what was sold and what needs to be ordered. I want this to be integrated with my accounting software so I only have to do things once.

I am on an impossibly small budget and it's just me so any help you can offer is greatly appreciated! Thanks.
