Hi Gazza,
Websites and servers are my dads thing, mine is social media sites, but if there is anything I can help you with pm me and ill see what I can find out for you.
What I can tell you though is you still own the domain, and your listed as the registrant, which is VITAL as far as ownershio is concerned. I had a few clients in my last position who came to me having their website taken off them by the web design company they used, all because they were not the registrants. Without being the registrant, you have no legal right to claim ownership of the website.
As for where its hosted, well thats entirely up to you. There are a whole host of great hosting servers out there but you must choose wisely. Those offering the cheapest hosting are rarely the best, because those servers end up being flooded with spam sites. Choose the wrong server and all your email could end up in peoples spam folders rather than their inbox.
But having said that, how often do you use your website email would depend how valuable that is to you. I personally use my dads friends servers in Thailand, for both of my websites, but there are some great ones out there who my dad always recomended so Ill double check who he recomends for you as I cant remeber at this time of night haha!
Just as a recomendation, wordpress is a great web platform for anyone to use when running a website of their own. Its predominantly a blogging software but times change and so has word press. Plus there are loads of free themes you can use to style the website how you want.
Mines a wordpress site, its nothing fancy, but it does the job and thats all i need. Im not Coca Cola so i dont need an all singing all dancing website.
If anything, concentrait on a Facebook business page, as word of mouth is the best form of advertisning, and using facebook well with your current customer base, is a great way of building relationshisp with your clients and maintaining a very loyal customer base.
Anyway, im going off topic, hope that helps and if you need any help hit me up!
