I would say if your look for "desi" girls from Indian subcontinat then you need to find guys who organise parties and "stage" shows etc. They can arrange all that for you including most bollywood, lollywood and tollywood stars. unfortuenlty i have lost contacts for 2 guys whom i knew some time back via yahoo groups.
B-Grade indian Drama or movie star was around £200 + you pay hotel fee. Same with lollywood stars.
Also SEE where the "dance" clubs are for Asian girls like "mujra" again you talk to the people there and you can see the dancers and go higher up with quality and fame.
Now i understand with your name and what you request the above is good.
Now direct answer to your question. Personally around 6 of the girls i have seen no longer advertise on AW. AS you might already assume Shit service espically to us asians.
Reema, Anita, Sunita, Deepa, Kartika also dont have there websites up last time i checked. Remember these names when they bounse back they will give you the best experience ever!
Reema was up north. Rest i dont remember too much.
Reema has made few videos and been on or in few publications like indian babes.
ONLY issue what i came across was she was too british and not "desi" enough for me.
She said stop being a "kuta" (dog) few times to mee and i called her a "kuti" which we both laughed about.
I would say read all of the forums just not for london and SEE what the rest of the community suggests.
