From the little information provided in the offer/advertisement it would appear that you require someone with expertise in helping fairly new businesses establish themselves.
Therefore, I would initially do an analysis of current position, in relation to your competition. This will help me gain a better understanding of what may be necessary to bring in additional clients for your business. Following this, I will make recommendations based on this analysis and standardised market research.
These recommendations could include items such as whether or not your website (if you have one) is optimised for search engines and user experience. If you do not have a website I will take you through the benefits of digital marketing and hosting a website for your company - whether you decide to have me create one for you is a business decision that we can come to together after objective analysis of the pros and cons. Other recommendations may include other mediums of advertising, such as posters/flyers etc., but as stated, I must conduct market and competition research to ascertain which method would be best suited to your business.
The reason I am the best suited to this task is because my main skills lie in marketing/branding. This is exactly what your company is in need of. Above I have stated the initial process involved in me undertaking the task, and I hope that this proves my understanding of the task at hand, while highlighting my ability to carry out the task.
