Hello, I am Mercy and it is pleasure to meet you here.
To be truthful with you , your budget is relatively small to the quality of work that I can offer you.
I can easily get the first 5 indices of each company from their websites.
1.) Who they are, 2.) Where there are, 3.) How big is the company, 4.) What they sell, 5.) How much it cost,
The last measurement of "their main strength & weakness" needs to be a critical analysis of their websites, social media tactics, and their other online tactics.
