New domain

Hello,
I have a blog and I want to change the domain. The new domain will be set by my hosting provider (domain, DNS, e-mails).
What I would like you to do:
1. Set the new homepage
2. Set the website on the new domain
3. New website Google Analytics settings
4. Assist me until all the new website settings and contents are online.
Could you please let me know your best offer and the estimated time you’d need to make all the necessary settings?

Best,
Lucian
