You need to get a web hosting package, a domain, and a professional theme. Siteground's basic hosting package starts at $155 a year and a domain will cost between $15-$20 a year. A theme will likely have a recurring annual fee if you want to get all the future theme upgrades from the developer. Expect themes to start from around $50 upwards per year. So basically, you're looking at just over $200 a year, all in all. It's a lot of money but it's a necessary investment. And it's tax-deductible.
