Chrome Extension SEO

I need someone to rank a Chrome extension on Google for a specific keyword. According to Ahrefs, the KD is 4, so I'd assume it shouldn't be too hard. That goal would be to rank the Chrome Webstore URL.

Note that our main competitor's extension ranks 3rd for the keyword (chrome webstore url) with a single backlink.

When bidding, provide the following:

- Estimated timeframe

- Your strategy (outlined, such as number of backlinks for example)

- Price
