Barn repairs needed - Windows, Gutters, Minor Structure

We have a barn that is over 120 years old, but has been well maintained. It has been built out a bit with an apartment and additional HVAC treated space, along with a small office space attached and 2 door garage addition for large farm vehicles.

There are 3 areas that I would like addressed - I am looking for qualified people to review and provide a quote for the following work:

1) Windows - Review / Repair / Replace / Paint. Some of the windows are of a newer style and should be in good shape, a few are older wood windows with a bit of rot and a couple of the storm windows may need to be replaced. These need to be inspected and recommendations made for bringing up to date, with a final coat of paint, as needed;

2) Gutters - They are intact, but a few are sagging a bit. They need to be cleaned out and adjusted. If replacement is need, please quote. May also consider cover system to eliminate future clean out requirements.

3) Structure - there is one corner which has an exposed vertical beam with has some rot - due to excessive water from blocked gutter. This post needs to be repaired - patched and the exterior redone (We do have paint for the finish).

Please feel free to respond with any questions. If you can only do 1 or 2 of the tasks, that is fine - the work can be allocated to multiple entities.

I will need some background materials on you / your firm, so please provide before we can move forward. Recommendations / Referrals are would be a big plus. Full address will be provided once recommendations are cleared. It is in Cedarburg, WI

Thank you for taking the time to consider this work.
