I'm an entry level C#/Java+Android developer and I cannot find a technical recruiting agency that will take on somebody at my level to match them with one of their clients. I have no idea how to find such an agency, Google has not been fruitful and I haven't found a question like this on this site.
The answer to your question is "yes", there exists such recruiters. I've generally found them to be regional specialists, and the greatest amount of them exist in regions that are having a considerable imbalance between demand and supply and there are more positions than they can find qualified candidates for.
If you are in a region where there are more candidates than jobs in your field, then there may not be such a recruiter in your region. It may be worth it to check into a local university/college chapter of a professional organization, check into Meet-ups in your area, and if you have a proper LinkedIn account they'll be likely to come to find you.
But this is extraordinarily regional specific. In parts of Wisconsin, USA I've had head-hunters contacting me and offering me a free iPad for referrals when I replied I wasn't presently in the market for a job, and it was a legitimate recruiting agency. There are development cooperatives, domestic "in-sourcing" groups, many insurance companies are opening internships to recent graduates in addition to students and even considering not-so-recent-graduates for the trial-basis programs...
And in north-western parts of Wisconsin there weren't even recruiters available for experienced candidates, much less inexperienced ones. There is no global or nationwide superpower of recruitment, and Google isn't really your friend in this one - you need to meet individual people at networking and social events, most likely, to get the real word on the street on who's looking and who's worth talking to.
If you are in a region with little to no active recruiters, agencies, meetups, tech/IT social gatherings, events, professional organizations, etc - and all of these aren't open and helpful to someone for entry-level positions with previous documented experience...then you are probably just barking up the wrong tree, and looking for something that doesn't exist in your region. Back to looking for individual companies who potentially have openings, make sure you have LinkedIn professionally setup, have a nice resume with something to point to as "I created this", etc. General type of stuff.
If you don't have a college degree in the field, things will be harder. If you don't have a college degree at all, things will be considerably harder than that and most people report more luck in looking into smaller jobs with smaller companies and trying to build up experience and a professional personal network of people they know.
