For #1 and #2, use your P411 and request a date through there because she can look at your profile.
#3, from my experience most women don't like to eat before a date, maybe meet for drinks first
#4, 1st call at crossroads and then will give you location. 2nd call from parking lot and will give you room number
Feel free to PM with any other questions.

1. For me, if I ask for the info, you can either provide me with it or move on to the next girl. I have a birthdate space on my contact form and it's mandatory (I prefer to see guys who fall within a certain age range). If you're really that worried about it, just put something close that will still tell her your age. For example, let's say you were born on 02/19/80. You could put under the birthdate space that you were born on 01/25/80. Either way, you recently turned 33.

2. You made a very good choice signing up for P411. I absolutely LOVE when clients are on there. It makes me feel secure and I don't have to spend a bunch of time prying for personal info or tracking down references. Oh, and it's nice when guys put a picture up, but it's certainly not a necessity. In any event, signing up there is seriously the best thing you could have done in my opinion.

3. I've heard of LE doing incalls, outcalls, and even "public place" meetings. You're taking a risk no matter what, but your risk is minimized the most by seeing an established girl with a good reputation.

4. First call tells you in what general area her incall is located, second call she tells you her exact location/room number/apartment number/etc.

1. & 2.  Since you are a P411 member, use that as your ref and find someone thru that site.  But, yes, many guys will give out their real names to a provider, however, it's better to give it to a site like P411 than several providers.  My profile has my pic on it, but I am wearing sunglasses and a hat, but I am single with no one to hide from.

3.  Scrap that idea.  If she is well-reviewed, all you are doing is spending money you do not need to spend, since she is not going to have lunch or dinner with you off the clock, you will pay for her time.  And it is no safer from LE.  Outcall is ok, if you are going to rent a room, but do NOT invite a provider you have not seen several times previously, which you have not.

4.  You've already been told what the 2 call method is.  It's just a safety procedure for the provider.

1.  Only volunteer what you are comfortable doing, but realize that it may be insufficient to get an appointment.

2.  I never put up a pic on my P411 profile when I had one.

3.  Going to a meal first isn't safer.  If you already discussed pay for play, you are already busted.  Static incalls have more risk, all other things being equal, yes.

4.  Two-call system means you call once to get the general vicinity, usually a street corner or a landmark.  The second call identifies where you are, and then gives you the full/exact address.
