Freelance Web Developer

We are a small business looking for a web developer to help with updates, changes and service to our website. The site does have an ecommerce component so the developer would need to be familiar with that. Most of the work to the website will be making updates to products featured on the ecommerce side, as well as seasonal updates and changes. Would like to see samples of work done. Looking for someone knowledgeable, responsible, professional and most of all reliable.
