What am I doing wrong?

[Itstiffany]

I just don't seem to be making as much money as girls online often say they are. I worked it out and I only made like 1000 in 2 weeks, I don't understand why. I'm in Liverpool, so it makes sense that I'd get less up here than the London girls but I would imagine it should be more than this.
I'm charging 160 per hour, 100 for half and 50 for 15. That's pretty standard right?
I'm definitely not unattractive or overweight.
Is there something I'm missing? 
I feel like I'm struggling every day to even pay my basic rent and bills and every day necessities, something I thought would never be the case when working this job.
I've been trying to do webcam modeling but you need a laptop and it's taking me ages to save up the money to even buy a laptop.
Does anyone have any tips?
