Illustration (cartoon style) with re-usable character

I am bootstrapping a new greetings card business, initially creating the designs myself - but time is short and I need to get some ideas turned into usable designs as soon as possible. These are not going to be cutesy hallmark card designs - think younger, rock music based audience.

Obviously I'm not going to divulge the actual design ideas in a public place, but I am able to provide style examples of the type of illustration that is required. Please only submit a proposal if you are able and quick.

There is definite follow up work for the right person as I have a small but available budget for more illustrations immediately if you are good! Pitch your price realistically (I'm not a slave trader!) - for example.. if you would be willing to do 3 designs for £100GBP, say so!

I'm willing to work with someone in any location, but due to time differences I will give preference to people contactable during realistic GMT hours (I work long hours so not necessarily during "office hours").

Here are a couple of links of the type of illustration I am looking for:

http://www.fanpop.com/clubs/danny-phantom/images/532309/title/danny-phantom-family-photo (not sci-fi specific, but I like the simple lines and expressive faces)

If you've read this far down, well done.

To make my decision quick and painless - please provide at least 2 illustrations you have done and tell me a bit about why they were done, and if it has been used (extra credit if it's verifiable!).
If you have portfolio/gallery anywhere online, I'd love to see those too.

Final work must be in EPS format (with AI/PSD originals) in 300DPI CMYK format. Printing is using a 4col process so no pantone specific please.

Without examples you're probably not going to get a reply so please don't hate me. I'm looking for good long term prospects and am spending cold hard cash to find the right people.

Full brief / discussion will be provided if you are awarded the work - but asking the right questions when submitting a proposal will get you some answers!
