I'm sure there is someone/shop near you that can do that. I bet *someone* you see all the time when out surfing (or other activities) has the skills and tools, even though you don't know yet.
You could have a rack built that fits your bike *and* the stuff you carry on it, like with mounts made just for your board, etc.....
If we were closer you could bring the bike over and we could probably weld a quick and dirty one up in a day, though it wouldn't be as "finished" looking as Bill's (that takes a while).

If you don't have the requisite fabrication skills, desire or equipment to build, take a look at Old Man Mountain racks; made in the USA and friends have had good service from them.
The catch with racks made like that (with bolt-on strips to attach to bike) is that the attachment strips and bolt on points can wiggle, eventually either breaking at the point the bolt goes thru the strips (usually on the rack end) or just working the bolts loose (fixable with loctite, possibly).
With small light occasional loads it's not a big deal, but with heavy stuff, or stuff that is long and sticks out the back or sticks out up top, the waggling of the load and thus rack put a lot of stress on it at all the points that bend.
The sturdiest rack for loads like that is one that doesn't have points that can bend, so that it is a single piece all welded together (or formed from a single piece, but I've not seen one of those yet), that connects directly to the bike, bolting into the rack/fender mounts (or on the axle, but that's a PITA if you have to take the wheel off, which is why we didn't do that for Bill's) with no intermediate pieces. If it clamps on, then as long as the clamps are part of the rack (not like hose clamps around it or whatever), then it's still essentially one piece and sturdy, but if the clamps are separate parts you still have the wiggle problem.
THe best way to do it is to weld the rack to the frame, but that's not an option for most people. :/
THe worst part about the wiggle problem is that it's hard to even see the wiggle if you just put the rack on and try to move it by hand...but put a lever-load on it and ride it and it'll still happen. If you have a camera that is mounted to the bike frame so it can't move, pointed across the rear/side of the bike to see the whole rack and the frame, you can see wiggling happen while you ride. Even a little bit of movement is enough to break it eventually if it gets enough stress over time.
Anti-wiggle is why I did the X on the back of Bill's rack. I would've done one on hte top too but there was some reason he needed it to be a ladder instead; can't remember any more.
Anyway, there's a lot of ways to make a rack, and the way I did it is just one simple one.
FWIW, I made a bolted together one from thick aluminum panels for DayGlo Avenger, and it outlasted the frame itself (whcih cracked at the crossbar of the seatstays, IIRC), because the panels themselves, while they can warp across their surfaces, don't warp at the bolted-together edges, even with a wiggly large dog (Hachi as a growing puppy) in the box bolted to the left side of it. It carried loads that I couldn't handle the bike properly with, and is still intact. (though it would probably still fail before a welded-together rack would--if I couldve' welded one up then I would have; didn't get to welding stuff till after, and it didn't break so I didn't replace it once I was welding stuff up). It did break several forms of attachment to the frame itself, though; I think the good (not cheap) stainless steel hose clamps around the chainstays and seatstays ended up the sturdiest, fed thru slots in the panels, but even those would break and have to be replaced.
