Business card design (logo already done)

I need a business card designed. It's going to be similar to the cards at $hire$[login to view URL] (Replace $ with S). See cards under "our cards". I want the same type of idea, but I don't want it to look like theres. The main thing I need done in this project is the background design added. Like the curvy lines and designs they have. I want it to look authentic, sort of like currency. Be unique and creative. It needs to look professional. My company name will be at the top, along with my logo. There will be an oval hole punch in the middle. My website will be along the bottom. The weight will be there in big numbers. Also need to have the purity on there. Things like weight, purity, etc, are things I will need to change, so I need to edit them. Also the backround base color. I would like to be able to play with it and change colors, without it effecting the design. I want a nice modern perodic symbol for it as well, sort of like the one used in the above link, but a little different and nicer. Something along the lines of this: [login to view URL],1311283626,8/[login to view URL] It will be credit card sized. Dimensions: (3.75 × 2.25 in) (1?8 in bleeds) Most of the work is done, it shouldn't be too long to put it together. This is really a small project that I'm not looking to spend a lot of money on. I am going to set this project as pay by the hour at $5 per hour, you decide the total cost for yourself. I will accept the best price vs rating of the worker. Thank you for reading. I will supply my logo, site, colors, etc after accepted. The end project I would like both a vector file and PSD file.
