Why not buy a normal jon boat? For most guys, a plain riveted jon boat is strong enough to withstand anything they will do to them in the marsh. What kind of terrain do you hunt in? Not sure where you're from, but around here in Iowa we don't see much for stumps and logs, mainly just cattail bogs and mud. We have used several boats with good results, a 14ft riveted jon (too small), a 14.5' custom built plywood/fiberglass "mud boat" (too heavy), and for this season, a 16' riveted jon. I have no doubts it will be plenty tough enough for us. Picked the boat and trailer up for $550, courtesy of an online ad. Everything was in pretty good shape for a used duck boat, a few dents here and there, but it even came with a new paint job. We will be overhauling it anyway to fit our needs (removing all bench seats, cabinets, floors etc), but if you are willing to look and do some work, you should have no problem finding something very suitable. Well, as long as you're not planning on jumping beaver dams and things like that. If you really think you need a welded boat, take a look at the tracker grizzlies, new or used. Haven't used one but I hear they are tough, and they seem to be rather affordable compared to the mud boats.
