Dear Employer,
Believing that you're looking for a budget website, I would recommend an option that would not be pricey for you in the beginning as well as easy to update into a high-end store at a later stage to save you money in the next phase as well.
Kindly let me know when we can discuss the details for your project in further detail. This will help me understand your requirement and give me opportunity to show you the options that we have.
Warm regards,
Anand Shah
