Design one sided postcards - 17 in total

I need postcards (x17 in total)designed in whatever format is needed so they can be printed on Moo.com.

- Each of the 17 postcards has a quote on it. I want this to be large.
- You will need to recommend the postcard design/typeface/colour(s) based on look & feel of my website . Perhaps give me three options to choose between for the first postcard - I will select the one I prefer and we can use this as template for the others. I like simple designs, coloured backgrounds with white writing, but i am not inflexible - i'm open if you think something else will look better.

- I am going to use the postcards as 'thank you' notes to clients & with complement slips.

- re timing - ideal if project could be competed this week if feasible.
Thank you.
