I have already done responsive websites. One of them was for a B&B, you could book a room, send an email and other things so. However I have also created my own website in a responsive way (If you want I send you the link), it is very nice. I know how to buy the best domain (value for money) because I had had to do it other times.
So for your project the first thing to do is to create the website design, so how you want to make it. The colours you want to use, for example, the style, the images you want to upload and other thing so.
Then I will show you a draft and we will work on it. So we can create a logo too, in order to make it easier to make people remember of you.
After that I will buy a domain for you (it depends on the cost if it will be just for an year or more, you will decide, i will show you the proposals.
After all i propose you to translate it in two langueages and i will check the SEO and control it by the search console of google.
Waiting for an answer in order to talk about the project, Francesco.
Ps. don't be afraid of ask me some questions if you want.
