Looking for a priest

Greetings,

We are a young couple about to get married in Estonia. We used to live in Prague and thought of having a small symbolic ring giving ceremony in a church in Prague in couple of weeks.  I contacted various churches and they all said a lot of paperwork is needed and at least 4 months of preparations since they were thinking of a full-blown official wedding and no other options. We are looking for just a symbolic ceremony, half an hour or so, without anything official, since we will already be married by that time officially. Just couple of words by the priest and us giving each other rings.

I was wondering, can anyone help me find a priest who would be willing to perform a very small ceremony, or direct me towards a church that would be happy to carry out this symbolic performance without any official requirements?

Thank you!
