Need help installing a garden pergola in my backyard

I'm looking for someone experienced to help install a wooden pergola in my garden. The structure and materials are ready, but I need assistance with assembly and securing it properly. Ideally, you should have tools and experience with outdoor installations. The garden area is about 5x5 meters, and I want the pergola to be sturdy and weather-resistant. If you have knowledge of local weather conditions and can suggest any improvements, that would be great. Looking forward to working with someone reliable and efficient.
