Hi Saidat001,
Thanks for your query.
If you are not technical enough to design and develop your store it would be better to hire someone with a reasonable price $400-$500.
To decide your store design you check the e-commerce template from envato elements or themeforest. Choose any design then you can assign someone to create a store according to your design and do some modification.
Feel free to ask if you have any questions.
Thanks
