Website to collect voluntary information from visitors - initial POC

I am looking to build a website that will help me collect voluntary information from visitors. The main purpose of collecting this information is for market research, so I am seeking to gather demographic information specifically. Additionally, I have a specific design in mind and would like it implemented. It is important that the website is user-friendly and secure. Thus, I am looking for a web developer who can create a high-quality website tailored to my project requirements.
