Kinna like woocommerce you can have product variation and you can set prices according to the variables
With the pro version you can link a dropdown menu to the price. https://wpplugin.org/downloads/contact-form-7-paypal-add-on/

I guess my question now is can you make more than 5 drop downs and can you make one drop down a set price and another drop down change the price like subtract or add to the current price. And can you make more than 1 drop down option.
This should explain it much better, something similar to unlockriver.com the form on the right in the home page
You can make as many dropdowns as you want. That is related to Contact Form 7 itself not the plugin. You can have one dropdown with a set price and another with multiple prices. The plugin currently does not have a way to add and subtract prices, however.
