Selling my product

Hi there I am, trying to make an ordering system done by choices.
So far I am using Contact form 7 with conditional logic.

This works fine for these choices.
The next step is I am thinking of adding on “PVB Contact Form 7 Calculator Add-on” to get me a price from selected choices and then giving them a value for contact 7, so I can then take the value across for a pay-pal for payment at the selected value.

I think in all I will use 4 plugins for this process. I have taken a look at wpforms, ninja forms and gravity forms. However I am worried about not being able to achieve my desired results.

I really appreciate and help and advice with this.
