AMATEUR illustrator to create some characters for book covers

I have written three unpublished books. One of these novels (my first) has been short-listed for several UK / International awards over the last few years. A literary agent took it on a few years ago, but unfortunately all the mainstream publishers said it was too dark / niche-market, and so it was never published. I am currently in the process of self-publishing these books, and am about to finish a fourth book, which is more mainstream and I strongly believe will have more success of getting published, based on the extremely positive feedback I have received previously on my writing style. A website designer friend has built me a website, and I am looking for an illustrator to create some pictures for four book covers. The intention is that the illustrations have a similar edgy style, so that when people see one of the book covers, they will identify the book to me, the author. If you are interested, please send me a private message, and I will send you more specific information, but essentially the illustrations I am looking for are: 1) A Bowling Ball 2) A Crab 3) Two Prostitutes standing next to a lamp-post 4) something depicting an office/work environmment In the meantime, I am attaching the draft homepage of the website that is being built for me, so you get an idea of the style and the area that you have to work with. I am not looking for detailed pictures, I am looking for simple/stylised graphics. This is essentially opportunity for a new/young/un-established illustrator to get their work featured, and be involved in something that is currently small but could potentially become a much bigger project in the future. Although I am unable to pay you anything significant at this point, if my fourth book or any subsequent novels are published, I GUARANTEE that you will be given first-refusal to provide the illustrations for these, and be paid per whatever the industry standard (I will put this in writing in a contract with you).
