Translation of "to contrive" into Spanish

I was trying to think how to contrive a meeting and here you are.

Estaba pensando cómo arreglar una reunión y aquí estás.

Sometimes it has been a bit of an effort for me to contrive that ending from a different subject, but not this evening.

A veces he tenido que hacer un esfuerzo para conseguir ese final en un tema distinto, pero esta noche no.
