Web Development Proposal Example (Marketing Site Rebuild)

Example job situation

A small B2B services company posted: they already have a 12-page marketing site on a page builder. The homepage feels slow on mobile, the contact form sometimes fails, and they do not want a new brand. Budget is a small fixed price. They asked applicants to mention one thing they would measure after launch.

Weak / generic proposal

Dear Hiring Manager,

I am a professional web developer with 8+ years of experience in HTML, CSS, JavaScript, React, WordPress, Shopify, and SEO. I can build any kind of website you need and I always deliver high-quality work on time.

I have worked with many clients around the world. Please check my profile and hire me. I am excited to work with you and I guarantee you will be satisfied.

Looking forward to your reply.

Why this is weak

• The opening could apply to any website job. It ignores that they already have a site.
• The skill list is a resume dump and includes stacks the post never mentioned.
• It never answers the measurement question they asked.
• “Guarantee you will be satisfied” is a claim you cannot defend in a cover letter.

Improved proposal

Hi — I would keep your current sitemap and visual design, and treat this as a performance and form-reliability pass rather than a rebuild.

I recently did a similar cleanup on a 10-page marketing site that was also stuck in a page builder: we reduced homepage JavaScript, compressed the hero image set, and replaced the contact plugin with a simpler endpoint so failed submits actually showed an error. I would start by recording mobile LCP on your live homepage and the form’s failing request in the network tab so we are fixing the real bottleneck.

After launch I would measure mobile LCP on the homepage and the contact form’s successful-submit rate for a week.

Two questions: are you able to give staging access, or should the first milestone be local reproduction only? And is the form posting to email, a CRM, or both?

Why this is stronger

• It accepts their constraint: no new brand, existing pages.
• Proof is one similar cleanup, not a career summary.
• It answers the measurement instruction they wrote in the post.
• The questions change the first week of work instead of asking for a vague call.

Personalization points

• Name the page builder if they mentioned it (Webflow, Elementor, Squarespace).
• If they linked the live site, mention one concrete issue you saw (unoptimized hero, layout shift, 404 on thank-you).
• Match their budget honesty: propose a first milestone, not a fictional full redesign.

Questions you could ask

• Can we get staging, or is production the only environment?
• Where should successful form submissions land?
• Is anyone else editing pages in the builder while this work happens?
