创建数据库以替换多个excel条目表单

I have been given a project from work and although I have built multiple databases before, for some reason this one is stumping me. I need to create a database to capture data which was previously being captured on multiple spreadsheets to simplify the statistics program at my company. Each spreadsheet captured key pieces of information, I've attached an example of each. Each sheet needs to be set up so that an individual can enter their information for their location and that one person (me) can enter the full company information. For example the hours form, from this form I need to capture the employee count and manhours, whereas from the district sheet I need to capture contractor hours, vehicle data (second tab), and performance data on a monthly basis. The final entry needs to be able to enter all of the counts on the counts link form in order to create a table similar to the link form. Can anyone help me figure out where to start, I have been feeling like hitting my head against the wall for about an hour now and cannot figure out where to begin.
