E-commerce Marketing and Sales Boost for Two Online Stores

I am seeking an experienced marketing professional to help increase the popularity and generate sales for two existing online stores: thejerseysworld.com and mamitascam.com. Both websites were launched approximately a year ago but have not received any proper promotion or marketing efforts since their creation, resulting in zero sales to date. I am looking for a freelancer to develop and implement effective strategies to drive traffic, enhance brand visibility, and convert visitors into paying customers for both platforms. My primary concerns are working within a low budget and overcoming the initial challenge of achieving market success. Proposals should outline a clear plan to address these goals, considering the limited prior promotion and the need to kickstart sales.
