Kim,  
First I am really looking forward to viewing your WEB site.
On the Picture issue, I would suggest you have both "glamour" and "natural" photos.  
Don't over do the glamour photos and maybe title the natural photos  as "the way I normal look/dress".  
Good luck with your new site.  

I don't know if it is really common sense or common knowledge, but I know that I won't be meeting someone who has just spent 6 hours at a spa, hairdresser, nail salon, etc. just to look like her pics, just for an hour with me.  Most of us do not want heavy makeup (transfers to us and our clothing) but prefer no or very light makeup.  
.
I don't do outcalls, but many Providers' ads say that they "Will arrive at your location dressed down to suit the situation." i.e., not looking like she just stepped away from a glamour shoot.  Likewise, incalls, but they don't need to mention appearance since they remain BCD.
.
Even K-girls might dress up in super-sparkly-spangly outfits but I meet them in more casual attire (i.e., sequins, maybe, but no super-sparkly outfits).  
.
You can definitely provide a MIX of glamour shots, boudoir shots, casual and natural shots. Pics should give us an accurate idea of who we will meet BCD.  And you can disclaim the glamour shots.  You can pretty much say what you said in your OP.  
.
I'd go with "mountain out of molehill" on this one.

... doesn't mean you need to fix your makeup and hair in a way that isn't anything like what clients will see.

Why not let the photographer focus (no pun intended) on helping you with poses, lighting etc that showcase your natural beauty?  Then no disclaimer is needed.  

Are nice. I like to see that a provider has a website and professional photos. Along with TER reviews and a presence on a verification site (TER and p411 are popular here in my city) helps me verify that the woman is established and legitimate.

I feel more skeptical about a provider who looks like they are not established and who appears to lack legitimacy. I agree with other posts that I prefer to see non professional pics so I know what to expect when I walk through the door, since you won’t look as glamorous as those photos, but again, having the $$$ for a website and professional photos along with reviews and being on a verification site all makes you look more legitimate IMO.
