Opinions ladies?? My husband's friend is trying to copy my ENTIRE wedding!!

Hi ladies, I'm newly married...2 weeks to be exact...and my wedding day turned out to be so amazing and more than my husband and I could have imagined. My husband has a childhood friend that is newly engaged and is trying to duplicate my entire wedding! She started calling us the day after our wedding asking us to share who our vendors were that we used so that she could book them. So far, she has booked our venue, DJ, and caterer. I don't mind sharing vendor information at all, but the thing that's bothering me is that she keeps asking us what our price tag was for everything...including what was our total wedding cost. I find this to be extremely weird and kinda rude, our wedding was budgeted based on several factors, including financial help from both sides of parents. Am I being unreasonable by feeling a little annoyed by all this? Should I be flattered that she enjoyed our wedding that much? Or should I let it go and help her plan my wedding all over again for her and her fiancé?
