Bridesmaid is being very helpful - help?

3 out of my 5 bridesmaids (including MOH) are all out of town. The only thing I requested from them is to stay with the palette of the dress, be at rehearsal dinner, and the wedding. I don't expect them to help me out at all, even the ones who are here locally. One of them was apparently very touched and offered to travel to the bridal shower and bachelorette (she has the means). She also offered to pitch in and hire hair stylists and makeup artists for the bridal party AND wake up first to get it out of the way. WHAT?! That is soooo sooo kind of her and I'm thankful and it just seems like a lot. She really put it out there that she wanted to help. I will probably find something to delegate if she requests but I guess I'm just overwhelmed...I'm not sure how to respond back too
