Logo needed for small business

Very small 2 person home business needs professional looking logo to be used on business cards, business shirts, invoice and car wraps. Company name is Fivestar Earthmoving & Contractors Pty Ltd Would like name of company included in logo. Also wish to have the following included...Indigenous Owned Company...and would like the Aboriginal Flag incorporated next to that some way (see attached). The company is for a driver of a grader machine (see attached for a picture of what a grader is) do not need to include a picture of the grader, this is only to help you get a feel for the company. Would like to pay $30 for design files, will need illustrator and jpg files on completion. Extra $10 for right person, who can provide 2-3 variations of the same design. Please include in your bid, draft of your idea, with watermark, and portfolio link. Any questions, please PM me and I'll get back to you ASAP! Many thanks,
