Approach to Market Unit and Fill Vacancy in Chicago

Hello all,

I am currently in the process of trying to fill a vacancy in my first ever rental unit and i wanted some advice.

Unit Stats
Located in Albany Park Neighborhood in Chicago
4bd/2bth Duplex with separate living and dining room
Fully renovated with brand new stainless steel appliances and hardwood throughout (tile in basement level)

I have been marketing it for about 3 weeks now and have done quite a few showings. I am trying to see if i can get it rented for the 1st of July. I used Craigslist and postlets (which puts it on Trulia, zillow and a couple others). However the main issue im seeing is that for a unit of this size it will take longer because you either need 4 roommates or a pretty large family. 

If i open it up to section 8 im sure i can get it rented ASAP since half my callers are section 8. However i haven't decided to go that route yet and its a last resort. I'm thinking of going with a leasing agency since im tired of driving home quickly to show the unit. If they find someone for me it will be the same as finding a tenant that wants to move in Aug 1st anyway.

Any input would be appreciated. Thanks
