Hi Sappjire, unfortunately this is just a process you just have to go through. As Andy said there are DIY options – WIX, SquareSpace or Shopify. There is the 1000 website option Swiftly. Then are cheaper paid systems like Zeald. And lastly custom built systems using WordPress or Silverstripe. In terms of costs you are stepping up from $0, to $10-20k to 30k+.
So firstly budget will drive what options you are looking at.
Next it’s about functionality, ease of use and design. What do you need, is it easy to use and maintain and lastly how can I design something that is going to be competitive and work.
On functionality and ease of use I would start by looking at all your competitors and seeing what they do. But then decide on the minimum set of features you need to get started and understand what you can upgrade to and add on later.
After you have decided what platform, then you need to design how it works. This might be the make or break part. Again use competitor sites as inspiration, look at how they work, the sections they have. Think about your customers and what they need. What is the easiest way for them to move through the site, how do you address their questions in that process?
Then think about the visual design – here you might need to use a specialist to help, how can you make the site look great, on brand, appealing. You might need photography or a writer to polish your copy and make it interesting, compelling.
Hope that helps.
