Hello,
The four areas that must be focussed on are:
1) The Target Audience
2) The Platforms to be chosen (eg. Google Ads, Facebook, Instagram)
3) The Quality of Ads and viewer engagement
4) Lead Generation
I will provide you a budget as per the requirements of your business in all these fields.
I work with a team of social media marketers who focus on restaurants in India. However, we are experts in social media marketing and can help you expand your business for a reasonable rate (Those which you won't get in US or even India)
Let me know if you're interested.
