Philadelphia Colocation For 1/2 Rack (or Less) At 401 N. Broad

I am shopping around for colocation options in Philly, preferable at 401 N. broad because that would be extremely convenient for me. I have read everything on this forum about Philadelphia colocation. I am having a hard time finding 1/2 rack or less. I wanted to see if anyone had any suggestions or other advice. Ideally I would like to have keys to the partial rack, but I know that’s asking a lot. I have contacted several companies. Here is a breakdown:

Called Broadview / ATX. The lady that answered had no idea what I was talking about when I asked for info on "colocation". She transferred me to someone’s voicemail. I called back a few days later and finally got through to a salesperson. He seemed annoyed that I was even bothering him with less than a rack, but told me that they have 1/2 racks for $475 (with 2 year agreement) plus $120/month for 1.5/megabits.

Called Switch & Data and left a voicemail. Never heard back. I am assuming they don’t do partial rack.

Called Cross Connect Solutions. Talked to a guy but he explained they don’t do partial racks and that a full rack is "around $1000 / month" depending on bandwidth, etc.. He then gave me the name of a guy from philpop.com, and said he could probably help me.

Called the guy from philpop.com, he said he would "see what he could do"?

I talked to Matt from razorservers, that’s a definite possibility.

I looked at burst.net prices and that’s also a possibility.

Emailed quonix.com to get prices.
