In first place excuses for my poor English.

I have the following shipping modules installed and configured by value of the order (higher value of the order = lower the value of shipping):

SHIPPING MODULES
- Flat module for normal orders (for orders less than 25.00€ , shipping = 4.00€)
- Freeoptions module for orders over than 25.00€ , shipping = 3.00€
- Clone of Freeoptions module, which named freeoptions2 for orders over 50.00€, shipping = 2.00€

ORDER TOTAL MODULE
- Shipping module for orders over 100€ = free shipping


All the modules work properly because they can only be viewed if the value of the order reaches the value set for each module.

I want to do is that once done the checkout only to appear the shipping method corresponding to the value of the order and that all other should not be viewed. how do this? the modules are well configured? is necessary to change the programming file \ includes \ modules \ pages \ checkout_shipping \ header.php? or is there another way to do this? I appreciate your help!! I'm new in this

below the programming of each module
