Hi,
Welcome to the greater Tampa Bay area -- hope you have a great time!
We have a lot of excellent guides here. I'll have to ask you what kind of fishing do you want to do when you're in Clearwater? Inshore for Redfish, Snook, Speckled Trout, ... or Offshore for Mackerel (King and Spanish), Cobia, Grouper/Snapper, Amberjack, ... ? That will make a huge difference as most guides/captains specialize in one or the other.
My recomendation is for folks coming to the area is to call a local tackle shop that books charters. You call them, tell the tackle shop what you want to do and what your requirements are, and they'll book the trip, calling the local guides that meet your needs. That way you don't chase the guides hoping that their calendar meets with yours.
You can give Tightlines Tackle in Tampa a call. They have a long list of guides they book for. Their number is: (813) 932-4721.
Some guides I've fished with here/know that are excellent are:
Capt Randy Rochelle (offshore) "Islander Charters". (727) 365-3218
Capt Tommy Ziesmann (nearshore) "Action Charters". (727) 432-0355.

Capt Rodney Martin (inshore)
Capt Jim Lemke (inshore)
Either will take good care of you and if they're booked, will refer you to other good guides.
To help the tackle shop and guide give you the best trip for your money, have some info ready when you call:
1. What your expectations are. Do you want to catch a specific type of fish, say a snook on artificial baits or even a fly, or do you just want to catch fish, species doesn't matter. Some guides are "live bait" guides and that works, but if you're looking to catch a 38" snook on topwater/artificial, you need to let the guide know.
2. Let them know how experienced you are. Most guides here are great with novice anlgers, but frankly, some are not. Some are not good with females -- it just beez that way! If you need a boat with toliet facilities, say so.
Tightlines,
PB
