Make sure you're not spending more than you can afford and don't get yourself in trouble.
I know the regular models I visit would never want me or anyone to do that - except maybe absolute arseholes or guys who go around saying how super rich they are, blah blah but that's a different story
But really, make sure you're sticking to your limits, it can be bad for a model to go from getting 7k per week from you then suddenly getting nothing because you have put yourself into debt. I hope that makes sense.. it's 2 am and I may be rambling
