Do you want an application that uses ReportBuilder ported, or do you want reports designed with ReportBuilder ported to say LazReport, or do you want the actual ReportBuilder product ported to Lazarus?
If it is the latter, I sure don't hope you shared the commercial licensed source code of ReportBuilder on Google Drive, because that is highly illegal. You can however let somebody port if for you in private with a contracting term that they may not share the ReportBuilder source code made available to them.
