We understand that you will be needing several order forms and 3 contact forms.
This is all possible with your account. Please see this guide on how to create your first order form and this guide here for help with creating your first webform to use for contacting.
If you don't want to take time designing them you can just as easily find and use some good ones by cloning them from our Template Gallery.
Then once you are done with all of that you will be able to add them to wordpress as you mentioned in your original thread or anywhere else for that matter.
Additionally it is important to make sure that for your order forms you use a payment integration and have a decent yearly plan to support the usage of receiving "payment submissions".
