Hey Fabiobui,
I am a rails developer with 2 years of experience working in web development and have good workexperience on bootstrap as well.
I'd worked on these kind of things earlier and can work this off as well. if you just want me to integrate the theme then that It can be completed in 4-5 days, And if you want to me to show you by integrating few pages in rails then it can take about 10 days and rest depends on the length if the pages.
I have also integrated these themes earlier in rails apps
