I have been on elance for over 5 years and rated in the top 30 out of over 160 000 designers. So, yes there are certainly high end designers/freelancers out there with a high end portfolio on elance. Try searching for freelancers in the category you are interested in and take a look at the top freelancers portfolios and see if they could be a good fit for your project. This is how potential clients find me. Its always a good idea to try and source the freelancers website as well to get a good feel for that high end that you are looking for.
