looking for sharepoint and sharepoint online developer

I am looking for a SharePoint and SharePoint Online developer to help me with my migration project. Specifically, I need help with migrating data from SharePoint offline to SharePoint online and intranet. The ideal candidate should have experience with customizing SharePoint sites and developing SharePoint workflows. The project has a flexible timeframe, so I am open to proposals from developers who can complete the job within a reasonable time frame. If there are any specific integrations or third-party tools that need to be incorporated into the project, I am open to guidance and suggestions from the developer.
