Corporate Tender Consulting Website

I need a WordPress-based website that presents my tender-consultancy and related services with a distinctly professional, corporate look. Visitors must be able to read regularly updated blog posts and start a WhatsApp conversation with me in one click from any page.

The build should include:
• A clean, responsive home page that highlights who we are and what we do
• An easy-to-manage blog section styled to match the overall corporate theme
• Persistent WhatsApp CTA buttons that open a direct chat
• Standard pages for “About”, “Services”, and “Contact” with a noticeable enquiry form

While WordPress is my chosen CMS, I am open to your proven theme or lightweight custom theme suggestions as long as they align with fast load times and clear corporate aesthetics. If you have ideas for extras such as a newsletter signup, appointment calendar, or live chat, feel free to propose them—just ensure the core blog and WhatsApp features remain the priority.

Please include examples of similar corporate sites you have delivered, outline your proposed timeline, and specify any plugins you plan to use so I can keep the backend streamlined and secure.
