Hi Heitor,
Hope you doing well!
I have gone through with the project brief about building a construction website & would love to offer you with one of our EXCITING OFFER: We will be giving you 03 mock-up designs on landing pages & than if you like our work you can hire us for the entire project.
Our designed website will be Mobile Responsive, Cross browser Compatible, SEO optimized etc along with all other key features that you want to integrate. Neat & robust coding will be done on your project by using HTML5 & CSS3.
Moreover, we will be giving you FREE 45 Days Website Maintenance Facility as an after sale warranty where our team will be removing bugs & maintain the whole site.
But the details that you have provided are not enough to get a more closer picture. Just open up communication on PMB to have clear collaboration on your project.( prices can get changed).
Thanks,
Shaaz
