If that goes well, you may find you're in love, and you can carry her off as your potential bride.
The reason the above option is better than just meeting and dating random women, is because these are ladies who have been sought after and trained in deportment, they are high quality, successful in their careers, clean, intelligent and beautiful. Traditional introduction agencies don't have that kind of woman on their books.
Someone with whom you can indulge in a fantastic conversation and enjoy a movie, share ideas and difficult moments, and even go undetected to events, where she will seem exactly like your girlfriend. Finding a real GFE or girlfriend experience is simply a matter of good research, and a bit of trial and error.
SO you'd need to not only cover her long term fee (packages available), but also provide her with luxury accommodations, and a decent expense allowance.
The most enjoyable way to meet truly beautiful women is to contact a very exclusive and upmarket courtesan companion agency like Mystique Companions.
