Selling Best captions for photographs

Why are you selling this site?
I do not have enough time to start advertising it. When I was creating it, I had some time, but now I have none, so I think the best option is to sell it.
How is it monetized?
It hasn't been showed to anyone before. It is just launched and tested if everything works fine.
I was planning to place Google ads or sell ad banners between pictures. I know that similar sites are very popular on facebook, I guess that it is possible to get a lot of traffic if correct actions woul be taken, but it takes time.
Does this site come with any social media accounts?
Facebook and Twitter.

What challenges are there with running this site?
Biggest challenge is to find good quality pictures that would be interesting for visitors to comment. But there is an option for users to upload their own pictures.
