ISBNs for My novels

Awhile ago I wrote a short story that many people told me should be turned into a book.  On the advice of a friend I participated in the National Novel Writing Month and completed my first novel.  It even won an "American Idol" style competition.  That one month changed me. I now have the writing bug.  I now have four (4) completed manuscripts.  My dream is one day to be able to quit my day job and just be a writer. I have learned a lot this past year about traditional and independent publishing.  I feel that being an indie would be the best fit for me. 

I have worked hard and I have resources for good editing and cover art.  The only thing keeping me from publishing is the cost of ISBN numbers.  For those who don't know each published book form (kindle, ebook, paperback, hardback) needs a unique number assigned to it.  This is for both protecting an author's work as well as  allowing places like bookstores and libraries to order a specific book. So I am asking for help getting numbers for my first few books (between $600-1500 for the necessary ISBN numbers). My hope is once I have a few books for sale that the money from them will pay for any future books.

Please help me realize my dream of being a published author.
