Book Cover - Bedroom Decorating

I am looking for a designer to provide up to 3 covers for an eBook titled 'How to Make Your Bedroom an Oasis - 5 Ways to Design Your Bedroom on a Budget'. Please note I am looking for a designer to work with LONG TERM and will need other covers very soon. The cover(s) can be photo's or drawings; however the photo's must NOT be copyrighted NOR require royalty payment. Free photo's only. Please keep in mind that I do require the following from you; A signed contract stating that this is a WORK FOR HIRE creation that you will own no rights to and that your name will appear nowhere on or within and that I will own all rights to including resell and distribution rights. This is not a difficult project and shouldn't take a skilled artist such as yourself very long so please bid accordingly. I am not looking to pay any more than $3-5 per cover. Barb
