HELP with a fanpage's price

Good night, i'm here to ask the right price for an active fanpage:

..i?m not the owner of the fanpage, but it comes from a trusted friends of mine; he is not in facebook?s business, so he asked me to sell the fanpage for him..

DESCRIPTION:
550k users; 2 months old; fans are from english countries expecially USA; 65% of it are women; a good activity like 8k visitors per day; publishing rights..

i think that 2$/1000 likes it's a good price for it..but i was wondering if i can ask more for this fanpage..

what do you think?

the most important thing when you buy/sell pages you have to concern about is the niche ??
What is the niche of the page ?

the niche..

it's the typicall women's fanpage.. title: text of love song ; full of sentimental photos and status..
