Sand Writing

So I am still trying tricks to allow me to put what I want where I want it. The next in my list of things to do is writing on the beach, unfortunately all tutorials I have read do not meet the level of finish that I want (you can tell that it has been photoshopped and badly). I appreciate the time they have taken to do their tutorials and they have helped a little (at least point the direction?) but if anyone has a really good one, or knows a trick or two about it please please please let me know.
