Help me flip my first house!

[Jessica Newman]

I bought my first fixer-upper which I wanted to flip for a small profit.
I have been posting it on free classifieds. I get hardly any responses from potential buyers.
Does someone has some advice where to post and how?
Are the chances much higher if a realtor is in charge of selling it?
Is it more lucrative if I have it remodeled first and then sell it for the ARV?
The house is located in a small town outside Pittsburgh.
