Add-on (Paid) Custom profile field output

Hi there,
this is what i like to have:

I created a custom user field for the wedding date in this format
It´s a one line textfield,
for regular expression i use this (maybe there´s a better solution):
^(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d$

Users can enter their wedding date.
Now, i want to show the upcoming wedding-dates on the sidebar or elsewhere on the frontpage, sorted by date.

Is anybody able to do this paid job?
Would be great!!
