Hey nice one! Gotta love the dropped domains...as long as you can retain the current PageRank it sounds like you will be golden! The link sales on that site alone would give you some decent pocket money.
Never get excited by what happens in 30 days. Just "be happy" When you can stay there for about 1/2 a year, get excited. In my industry, half the companies who hire a professional to make a site and get it high in the results seem to do just that, for about the first month. And 97% of them that rise up that way, fall off the radar within short order. Only a speck of them hang in there. So the important part is the long run.
