website damaged by malware – seek expert advice

Hello,
My website was hacked & infected with malware. A friend removed the malware, but apparently also removed some of the WP CODE. The template was damaged. I am recreating the site with a new template, but when I type in the url a very ugly version of the previous website appears. In addition, some people are getting “warning” signs when they type in the url – https://www.solutionsmapping.com

I have installed WordFence and have created a new username and password – and see that the site is under constant attack. I think this may be because it was compromised.

I need to know the best, and most economilca way to proceed: 1) rebuilding the site on another host. 2) getting a WP expert to ID the missing code and reinstall 3) ???

Thank you.
