Hello,
I can design and create you the Immigration consultancy firm website, however Working on WIX will be not a reliable option. I would suggest WordPress for this job, It's great that you already have a 'coming up/under construction' page built, it will be the development even fast.
For the Logo I can design that as well for you.
I am a UX/UI web designer and developer so you don't need to worry about the user-friendly design, I will make sure that you will get the quality work.
I would like to invite you to chat so we can have a reliable and effective communication.
Regards,
Ammar s
