Suggestions on how to best sublet office space?

[Carl Fischer]

I am looking for suggestions on how to best sublet office space. We moved out of our rental space with 2 years left on our lease. I have had it listed with 2 different realtors with little to no action. I tried to get the complex leasing agent to help but they declined to help because it would be competing against themselves. I have talked to other tenants in the building already and they are not ready to expand. Realtors say I am in a bad place because 5,000 sq-ft is too small for a bigger company and too big for a startup business. My lease does not have an out penalty as I am on the hook for the full 22 months, evidently in Blue Bell Pa it is standard practice.

1. The area has vacant space but is in an ideal location at intersection of interstates. (near Philadelphia)

2. The price is less than asking price in the complex.

3. The owner of course will extend the lease if a company wanted additional years.

4. Nice finishes in the building class B+ to A(lots of glass 2nd floor

What else should I be doing or looking for? Any suggestions? 

Thanks

Carl
