Hi Paulos99,
Welcome. you have started an interesting threat here. As a freelance web developer my advice is always the same. Never rush into this and breath. Ask yourself a few questions before starting out and looking for a web developer.
what do I want to achieve with the website?
Who is my main competition?
What does success look like in a years time?
Will I need a bespoke site or a build your own like Wix?
What is my budget and what am I comfortably prepared to spend?
I suspect that you will need a fast loading and bespoke website that can be easily be scaled up as your business grows. Wix, SquareSpace and others are good for people wanting to start a very small business and not wanting to grow it.
Yes they do look awesome compared with others but you may find in time they can be restrictive and extending them to your needs may become a problem in the future as your business grows.
Finding a good freelancer with a reputation can be quite a minefield as the competition is so great amongst us. But getting one to work with you can be a godsend and finding one that will not abandon you after the site launch is what you want to go for.
Do a search for freelancer web developers near me
Read over their website/blog
Check out their portfolio and contact the site owners for their experience
Ask if you will get a bespoke site that's easily extended and not a over-bloated downloadable theme.
Search for reviews on Trustpilot, Facebook, LinkedIn, Google, Clutch.co, Yell and others
There is a lot more you can do but I recommend that you first decide what it is you want to achieve. Find out your competition by searching google for the keywords and phases you want to rank for. Come up with an initial budget and marketing plan for the site that your happy with and be honest with the freelancer about it. After choosing the Freelancer, get in touch with the owners of the sites he/she has built and ask them questions about what they thought about said freelancer.
The list can go on and on but I hope that I have given you some food for thought here.
Best of luck.
