Hi,
I can help you. I read your job description, although I cannot do all of the mentioned tasks from 1-5 but your encouragement made me offer my service. I offer you website SEO audit and 10 competitors research.
I will provide you a detailed SEO audit report, in which I will mention what needs to be done on your website in order to increase the website rank in SERP. I will give you suggestions to improve the user experience, mobile friendliness, and page load speed. If you do the onsite SEO right, you don't need many backlinks (off site SEO) to increase the rank of your website.
Other than that, I offer competition analysis of your top 10 competitors. I will send you their SEO data, what strategy they have, what kind of backlinks they have build, what title,description they are using, how is their website page load speed and usability and much more.
If you don't like my work, I offer a refund to my clients. Although, my clients' satisfaction is above 90%. But here and there some client's expect so much in very less price and get offended when see the results. But don't worry, I give you my assurance, you won't regret your decision. I will do my best.
Let me know if you are interested in my offer. We can further discuss this project in the chat.
Thank you for your time,
Azib
