Based on my couple of visits...don't worry about which floor. Spend sometime walking through all floor and seeing all the collection and then decide. No one intimidates you if you are walking out after spending time.
That being said
2BGF starts from 1700. So that's aunties.
2B1F better than GF. 2.2 to 3.5.
1B2F I think has the best ambience...lights and stuff.
Overall first building seemed to have more young girls. That's just my impression.
Basically you can walk into any floor and there'll be someone to find your needs and budget. Except for 1700 bracket I think every floor SP arranges all sorts of budget.
If still want SP number, I'm PMing you one. When I went first time I didn't bother with SPs. Second time this SP gave the number...He was in 2BGF.
