Customization of Gravityforms with Woocommerce

We're developing a box sending subscription page. We use the gravity forms, I need to do the following workflow / steps for the order: 1. Choose by customer if he has a product A or product B 2. Enter some infos for product A or product B (Textfield, dropdown..) 3. If neccessary add more product A or product B to the order (by clicking a button under step 2 like "+ add another product A" "+add another product B") and then the neccessary fields appear under the already filled out ones again (step 2 with the infos) Endless adding of more product A& product B possible. Info needs to be seen in the backend. 4. Choose subscription level 1, 3 or 6 month with it's own prices 5. Make payment by wirecard (make sure, if more product A or product B are added, the price is changed and also seen in the backend) 6. Subscription is sucessfully entered in the backend 7. Subscription is charged monthly for the subscription time. So I'm looking for a dev who can create this in combination with woocommerce. I have the gravity dev license, also the subscription extension fro woocommerce, the gravity add on extension from woocommerce and the wirecard extension also.
