Company Letterhead Design in Word

Hi, I have attached a sample design that I would like you to use as the inspiration for creating a premium Microsoft Word letterhead for my company, Solar Mission Australia. Please note that the sample is only for design inspiration. I would like you to improve it and make it look more premium, modern and corporate—similar to the clean branding style used by companies like Tesla or Apple. Requirements The final file must be created natively in Microsoft Word (.docx). Do not use the design as a background image. Every element should be created as editable Word objects wherever possible. The template must be fully editable so we can use it for all company correspondence. Header Please include: Our original Solar Mission Australia logo (provided). Do not recreate or modify the logo. Use it exactly as supplied. The company name should retain the same blue gradient effect shown in our original logo. Position the company name on the top right. Directly below it, include the slogan in gold: Powering Australia's Future for Generations Below the slogan, add the following text in two lines only: Harnessing the limitless power of the sun to energise Australian homes, businesses and communities — today, tomorrow and beyond. Please keep the header compact and elegant. It should not occupy too much vertical space. Watermark Please use only the light bulb graphic from our logo (without the "Solar Mission Australia" wording). Place it in the centre of the page. Make it very light (approximately 5–8% opacity). It should not interfere with typing. Footer Create a clean, premium footer containing: Address, ph, web and email Please include simple modern icons for each item. Certifications At the bottom of the page, include very small versions of: NETCC Approved Seller logo Tesla Powerwall logo These should be subtle and not dominate the design. Design Style I am looking for a: Premium Minimal Luxury Corporate Modern Clean appearance with plenty of white space. Please avoid heavy graphics or oversized headers and footers. The design should feel professional and timeless. Deliverables Please provide: Microsoft Word (.docx) Fully editable template Compatible with Microsoft Word (Windows) Ready to use for company letters, employment references, legal correspondence, quotations, invoices and other official documents. Actual vector file , png of logo can be sent once confirmed Budget: AU$10 Thank you. I look forward to seeing a premium corporate design.
