12 Grain Bread Help

Hello there, 

After looking rigorously at the extensive information and fantastic community I'm decided to become a first time poster here on the forums. 

I've made maybe half a dozen loaves of bread just in a typical bread machine and I like the bread but it just doesn't compare to the fantastic artisan breads available at bakeries at the current city where I'm a student. Back at home(not at the city) I've always feasted on fantastic 12 grain bread with flax seed from a local baker but here in the city I cannot find this bread anywhere. So I'm going with the solution of attempting to make and learn to bake it myself. 

Even though no 12 grain bread exists at the city bakeries, I was able to find 12 grain flour with flax seeds for a reasonable price nearby. I used the suggested recipe with the flour and used my bread machine and I was somewhat pleased with the taste and look but it still didn't compare to the bread I crave back at home nor any of the bakeries around. 

In addition, I have recently purchased a baking stone and now want to transition from the bread maker to kneading and baking my own bread to become a bread artisan enthusiast. 

I was wondering if anyone has any fantastic 12 grain bread with flax seed recipes I could try out for my first hand made loaf. Another question is before my baking stone arrives what can I bake my bread on in the oven? I do not have a bread pan and was wondering if a cookie sheet would suffice? 

Here's an picture from Google images of what I am aiming for. I also would be interested in a 12 grain sour dough style as well. 

Any replies, help and clarification is immensely appreciated,

Thanks!
