Building first quiver

I've been out surfing all summer this year, and I've developed pretty well, I'm relatively confortable trimming down the line on unbroken waves and can catch waves with relative ease. I've been borrowing boards, starting with soft tops and recently riding an 8.6x17x22.5x14.25 southpoint minitanker with thruster fins (although im not a huge fan of this board). My issue has been finding information on buying boards for my body type. I'm a division one athlete, and am 6'3" and 225 pounds, with really low body fat and in great shape. I've also been snowboarding my whole life. I'd like to get two boards, one longboard that is a small wave catching machine, since I'm from the northeast and surf mainly in the summer, and then one that is shorter, thinking along the lines of a fish, that I can use to really push myself and develop, trying to transition towards a, on better days. Any suggestions would be great. Thanks
