You might want to re-visit your casting form. When I guided I found that very few people understood the dynamics of casting.
Three solutions:
Free Fix: Go to the C-Town Breachway, or the canal some moring and watch how those who cast well do it.
Medium Priced Fix: Buy a
Ron Arra book or video - I sell them and so local baitshops and other S-B sponsors.
High Priced Fix: Hire a guide but be up front that one of your goals as part of the trip is to improve your casting distance.
Watch out for people who say the fish are at your feet and therefore casting distance is a non-issue. You're looking for a solution.
