Write a VBA macro

The services of a macros writing specialist are required. You need to write a macro - create an excell file in which you can select a specific bank, reporting period, and balance sheet items. After that, the dynamics of a particular item or items (for example, net profit, staff costs..) for a given period (for example, six months) will be built.
There is a certain number of exel files of the turnover and balance sheets of banks, in which each tab is a separate bank. The name of the exell files differ only in the months for which this report is made. The entire balance sheet structure is standardized for all banks in all files.
