How to check this company and what they really mean?

Hi,

I ve got this message from company.

Don't exactly know what they mean. Did someone has similar experience.

My products are handmade jewelry.

Hi there,
 
This is Larry WesFranco from Gimmegamma. We represent ShopLC.com, one of America’s popular live-TV marketplaces for jewelry and fashion products. Our cable channel reaches 77 million American homes.
 
I’m wondering if Shop LC could sponsor a Guest Post on your website?
 
Our work has been featured on techradar
 
It’ll be great if you could share with me the advertising opportunities.
 
Thank you for your time! I look forward to collaborating with you.
 
Cheers!
