Need help for planting my terrace

I build a new terrace on the southern side of my house. To make it look more cozier and friendly I made a plan for an integrated green area. Since I have no experiences with planting a garden or a green area I will need a great amount of help with that. I already bought potting soil, rolled sod, flower seeds and different types of flowerpots. As I pictured above I made a full plan and with the material I allready got there is really just the handwork to do.

I need someone who knows exactly how to plant the different types of flowers and how to lay out the rolled sod in a proper way. It would be great if the person could work with me together, so maybe I could learn a bit about gardening and have a little instruction for works I have to do in the future.

Here is hoping for good offers.
