    I already own the domain and have WordPress installed; now I want to turn it into a polished finance blog. All current posts live on Blogger and need to be migrated cleanly into WordPress, keeping existing URLs where possible to protect SEO. The visual direction is firmly professional and corporate—crisp typography, restrained colour palette, spacious layout. Once the theme is in place I’d like the site structured around clear categories (e.g., Investing, Budgeting, Tax, etc.) so readers can browse by topic. Core pages and elements I expect online and working: • Landing page that highlights the latest or featured articles and a clear value-proposition banner • “About Me” page with room for a headshot and short bio • Privacy Policy page (I ca...

    I need a series of concise tutorial videos that clearly demonstrate my code in action. The goal is to help brand-new customers understand how each feature works, so the recordings should feel welcoming and straightforward even for someone seeing the product for the first time. Each video will focus on a single feature walkthrough—from opening the project, stepping through the relevant functions, to showing the finished result—highlighting practical use rather than deep theory. Good screen-capture quality, a clean voice-over, and on-screen callouts where helpful will make the explanations land.

Content & flow • App features – concise copy paired with lightweight imagery or short SVG animations so the page stays fast. • Zip code availability checker – a small JavaScript widget where users enter their ZIP and instantly see if the service is offered in their area. A simple JSON or CSV lookup is fine; just keep it snappy. • Contact form – name, email, message; routed to my inbox with basic spam protection (reCAPTCHA or a honeypot). Look & feel White space, muted typography, and one accent color that matches the app icon.

When the guest submits the offer you take card details with Stripe, create an authorisation only, and park the charge. All bids drop into a simple...
