NEED HELP WITH A GUIDE

I need some help I am looking for a guide around Galveston or Freeport to take out 5 to 7 people. I am looking for 2 days for 12 hours or maybe 1 day for 24 hrs. Please tell me of someone you have used that has good rep. and has a decent boat. I do not want a small boat that will get thrown around and I am not looking for a monster. It is a business trip for clients and so I need to make sure it is in budget and they have fun. I know the seas can get rough in the fall so that is why I am thinking of maybe a little larger boat. I thought one of the captains that are slow right now might want to make a little Christmas money. Thanks steve
