Arranged marriage and Need Letter

I got married last July, through arranged marriage which has been a blessing for me and my wife, do you guys have any advice on what I should be on the lookout for or what I should show, perhaps communication with my wife

Secondly, my uncle and father-in-law who set-up me and my wife, want to write a joint letter saying that they set us up and their both fully support our marriage but they have no idea what to write on the letter or how to write it and nor do I, perhaps you guys could show me template or samples of where I could get this from…..

Many thanks guys and I appreciate all the help
