Welcome to JustAnswer and thank you for utilizing our services.
The domain name seems to be expired. Is that one of your problems?
Ok it depends. There is a variety of website hosting models from which your consultants may have chosen to host the website.
Is there any additional information that the consultants gave you when they handed over the website if they did hand it over?
Ok, the most important information to find out is, with whom is the domain name bikeocalamarion.com
registered with among GoDaddy, Domain.com, NameCheap and Network Solutions or any one if not one of these so that you can renew it with them.
The website content can then be hosted anywhere including your premises.
