Welcome!
First, you should get verified provider status so that you can research these kind of topics in the ladies forums...it will also give you the ability to post ads and make known your availability without compromising the integrity (ha!) of forums where ads (or ads disguised as threads) do not belong...Here is a link on how to achieve that:

There is a wealth of information available, answering any and every possible question you may have about providing in Dallas, or anywhere else for that matter...just search around a bit and you'll find what you are looking for!
Again, welcome to Dallas!
