As a players for 15 years and being sinked for more than 6-7 times, I would mostly agreed with what c-hing suggested. My current mode is similar to yours but I won't request to privatize her cuz' unless you can stay with her every nights and days OR it's just impossible or not worth it. In this regards, I would only retain those good ones (usually those not frequent report to work) for private sessions and each time I would just pay them standard price (5 for quicky /8 for overnight). Offering 3-4K per week is high price unless you are fully privatized her. I had a few before and the monthly cost is 10K-15K per month. However, many PK taiwanese can really give big $ (>$20K per month).
