Hello
I would suggest to use wordpress for this project as it is the easiest to learn and manage CMS system out there, and from simple presentation site, to more complex online store it can handle everything. Right now not sure what type of hosting you have, but for a self hosted wordpress site you might need more than godaddy. To be sure I need to see the hosting specifications you currently have.
I usually work with building a child theme for the site, based either on an existing professional theme from themeforest or based on some free theme. I would suggest to go for a themeforrest theme, mostly because behind the very best themes there is usually a large team of developers, who can toughly test the chosen theme to work with any device or browser, while you can see how for about 50 usd there is no way to have time to test a theme to be perfect in any environment.
You don't have to worry that your site will look "just like the other" because these themes are mainly provide the structure of the site, the content is of course entirely yours (text, pictures, logos, colour schemes etc.)
Feel free to hit me up for a chat if you are interested, I am happy to explain you everything you need to know, before even jumping into the project, and help you decide what's best for you. You can check my reviews here before you choose.
My bid also includes so called "basic training" so you will be able to manage the site by yourself.
Best regards,
Eva
