Create Your Own Package?


I have a Table that has Services with costs associated. I have another table that has about 6 different “packages” based on said services. Can I create a form for prospective clients to request services and allow them to create their own package? Ideally I’d like them to have the option to pick one of the existing packages and add a service to it, or completely pick their own services, and upon submitting the form, I have their contact info and can create an invoice/project from there.
