I need to get data from my users on the jobsite back into our SharePoint site. Any suggestions?

Yes! If you are an O365 shop, I suggest checking out PowerApps. PowerApps will allow you to effectively create mobile applications, without code, and deployment is quick and straightforward. Finally – we can say a true “good bye” to InfoPath forms. Take care however, and understand that PowerApps requires the user to have an O365 account to connect with!
