Official Website & LLC Creation in Texas

I'm looking for a professional web developer and business consultant to help me set up my official website with functionalities for product listing and sales, as well as displaying company information and contact details.

Key Requirements:
- Design and implement a user-friendly website
- Integrate e-commerce capabilities for product sales
- Ensure the site has comprehensive company information and contact details

Additionally, I need assistance with the creation of an LLC in Texas. The ideal candidate should have experience with:
- E-commerce site development
- Business formation in Texas
- Familiarity with product listing and sales websites

While I can handle the setup of my Amazon account, I will need help with:

- Obtaining an EIN number
- Acquiring a seller certificate

I would prefer a professional who is not only skilled in website development but also possesses a solid understanding of business operations.
