shark fishing in south pedre

Hi guys, hoping for some help here...
I'm thinking, or will go down for a few days fishing in south padre in August.
And have a few questions.

1.how is shore fishing down there for sharks? Have my florida gear so it's not beach casting stuf,
So is the fish go kinda close to the shore?

2. In san diego did I rent a small bay boat by my self, can you do it there too?

3.and a good sharkfishing guide? In smaller boat and for a ok price?

And anything else fun to fish down there? My plan is 3-4 days.

Thank ya all so much

Lots of good sharks on the beach. All within 100yards or more off the beach. We do shark fishing charters as long as the weather is safe for us to do so.
