Design a eye catching logo for a Women's Retreat

Mujer Fuerte y Valiente (Proverbios 31:25)

We are a church organization and we are having our women's retreat for 2018. The title or theme of our retreat will be "Mujer Fuerte y Valiente" (which translated into English means: Strong and Courageous (Brave) Woman). We would like to add the Bible verse that will go along with the theme and it is "Proverbios 31:25." I don't know if it's a good idea to add as a subtitle to the logo: "Retiro de Mujeres '18" (which translated into English means: Women's Retreat '18). I would like to get an expert opinion on that. It is an all women's retreat with the idea of the woman having a character trait of strong and courageous or brave woman nowadays.

Just have a question for you. How much more would it be to get the same logo that you are designing to use if for a t-shirt print off? Now we have our own print shop that we deal with but we would need the file format for t-shirt print. How much would that cost? Thank you very much.
