For the past few months I have spent some time with lady that I am considering offering to go exclusive with. Probably seen each other ten times. We have a very good vibe, albeit with no delusions about things becoming some broader romantic relationship.  

I read some of the older board threads on this topic and thought some of the insights offered were very interesting. One thing that I am curious about and did not see much comment on was the financial component. For someone with an hourly donation of 900, any thoughts on what an appropriate monthly arrangement might be? Her situation is such that she works at another job, albeit on a project by project basis. I think she probably works 5 - 7 times a month seeing guys.

Guys, do you have any ideas here?  

Ladies, any experiences you might share if you have ever been in an exclusive arrangement?  

Thanks in advance for any comments.

You do the math...900 times 5, or 7= what she is ideally looking for each month, so ask yourself are you willing to supplement her income?

Do you expect her to be exclusive, or stop posting ads?  These are ?'s you should really be asking the provider personally, not the public.  I have had several sugar daddy arrangements, and everyone desires are different.  My advice ask the source.

But not knowing all the details such as will she still be allowed to see her 5-7 guys a month (that number could probably be close 10-15 a month). What kind of allowance will she be comfortable with. Does she want an apartment or car or???....Will she be allowed to have her boyfriend over when you're not around...there's a ton on questions you'll need to address with her. If you go to one of those SB/SD sites you'll get an ideal of what you could be into as far as dinero go.
Ask and ye shall receive

Does she wanna go exclusive with you?  Does she has other guys who might be her regular with?

When you get too comfortable with a girl you let your guard down and sometimes it doesn't workout right

As the saying goes, if you have to ask, you can't afford it.
