I will translate any text up to one page from English into a hidden code

I'm a hobbyist who loves cipher codes. So I'll write up to one page's worth of text from English into a hidden cipher code. Your message is almost impossible to crack unless you know a lot about the cipher, or else you know the key. It is VERY secure. Pretend to be a spy like Chuck! Tell someone you love them in a creative way! I say 3 days at max, but I expect each job to take less than that.
