Many years of missed fasts

Q: My age is 45 now. I became baaligh at the age of thirteen. Without any reason I was not fasting in Ramadhaan, until my age of 22. But after that my life changed and I began to lead a pious life. As I'm a lady I miss rozas due to periods every ramadhan. Also I left full rozas in 2 Ramadhans due to pregnancy. I'm doing qaza of my rozas since the age of 22. But it has become a huge burden upon me as I have to make qaza of hundreds of rozas and also with the mudd that should be given to poor on each roza. Mudd also doubles each year as I could not make qaza of these hundreds of rozas in one year. I am a follower of the shafiee madhhab so I request pious solution for this big problem.

Asking a buzurg to make dua for one

Q: Is it allowed to go to  a buzurg or a highly religious person who does a lot of ibadah and ask him to pray to Allah about my problem. And can we supplicate through an intermediary i.e through tawasul of a righteous one, living or dead e.g through Sheikh Abdul Qadir Jeelani. And I also want to know is it permissible for men and women to visit the shrines of say Sheikh Abdul Qadir Jeelani and other without committing any shirk and praying to Allah directly there?
