Newbies are better off staying with reviewed providers, BUT. I am an experienced hobbyist that try newbie providers if they strike my fancy. I look for a number of features in their ads and behavior. If a newbie wants to give a newbie provider a shot, these are items that my experience say must be heeded.
-If she has an ad with an email link, I try emailing her a base email stating interest and whether she is available for my type, ie, race, weight, age, profession, et al. If she does not answer the email, I move on. She is either a quick buck artist, will not see me based upon an issue with my race, weight, profession, age, et al, or is disorganized. The quick buck type will rip me off. The disorganized type leaves a trail that law enforcement will eventually become wise to. I don't want to spend time with a provider who has an issue with my appearance or profession.
-If I do a brief email or call, I propose a date on a day other than the one I emailed or called. If she does not respond to email or snaps that I can call her when I am ready to visit, I move on. No email response brings in the problems listed above. Irritation with me not wanting to visit same day implies that the provider is a quick buck artist or is not particularly discreet about who walks into a room with her. My experience has taught me that providers that are pleasant and willing to see me on a future date are legit, they may not be top notch, but they are legit. I don't waste a provider's time with long emails or phones calls. I am plain vanilla during the contact, nothing sexual is stated or implied.
-I look for multiple ads from the provider. I look to see whether the provider's age changes in ads. If a picture is posted, I examine it to determine whether she hides features that don't need to be hidden. I like an age range for providers I visit. I check a provider's ad to see whether she hides her age, or as pointed out, mistates it. Multiple ads are not bad, per se, but I examine them for consistency, pictures that match, age that match, looks that match, et al. If a provider hides her age, the possibility is that she is older than I desire. Or that she is underaged, making her of no interest to me from the perspective of her providing services to me.
