As to dedicated crusading chapters there are a few around most not as well known as the black templars, but some such as one that comes to mind is the onteresting army or the charcharadons (space sharks) the badab war talks of how they are a crusading chapter which has out into deeper space explorating and claiming world for the inperium.
Apart from that go wild, if its a new chapter write some fluff, paint some models and onward. (Also post it here on heresy always like some good models).
