Invoice PDF Generation with Java Spring Boot

I am in need of an expert who can assist me in generating PDF invoices using iText7 in a Java Spring Boot environment, though I understand that this question was skipped. The project involves:

- Utilizing Java Spring Boot: You should be well-versed in Java, particularly Java Spring Boot, to handle the backend development of this system.
- Employing iText7: You will need to have expertise with iText7, a PDF library, as the tool to create these invoices.
- Integrating Invoice Information: You will need to include client's name and address, invoice number and date, and an itemized list of products/services on the PDF invoice.
- Formatting the Invoice: While I understand that the specifics of how the invoice should be formatted were skipped, I'd appreciate if you could provide a simple and minimalistic design.

The ideal freelancer for this task should be skilled in both Java Spring Boot and iText7, with a background in PDF generation and a good eye for design. Clear communication and adherence to deadlines are also vital.
