Check with Dusty Dooley & Capt on the Catfishing section. I think Dusty also does sandbass trips in the summer. I think they are around $60/person maxing out at 6 guests on a pontoon boat.
If you want to stay in the $25 - $30 range, there is Galveston Party Boats and Williams Party Boats in Galveston Bay.
