This low sec Venture can do it all - huff precious cyto gas, hack sites, and pop unarmed explorers.
The following is the default "travel" fit. With V skills and a cheap AR-802 implant, it has enough probe strength (80.5) to scan down level IV sites. It boasts 123 dps, two scrams and 4289 m/s velocity when overheated. The locking time vs a frigate is 1.9s, and align time is 2.99s. Its tank is absolutely minimal, only 975 EHP, but you get an innate 2+ warp core strength defence to help warp you out, should your victim fight back.

Huffing gas
Dock up at a station, replace guns with gas harvesters, and swap the scrams with the burst jammer and multispectral ECM. They are your defence in case you're jumped while huffing.
Hacking
Replace a scram with the relic or data analyzer. If another explorer warps into your site, you still have another scram to point him. You can also replace the second scram with the burst jammer if you're paranoid against stealth bombers. Your align time is 2.99s, so an Astero shouldn't have enough time to lock you. Turn off your MWD while hacking to keep your align time at 2.99s.
Hunting
Most people assume that Ventures are harmless. If an explorer sees a Venture warp into his site, his suspicion won't be as high as say an interceptor or an Astero. With the travel fit, you warp into hacking sites and pop a target as quickly as possible. Only target unarmed T1 and cov-op explorers. If they fight back, warp out. Because of your ore hold, you can also target Ventures and Prospects and loot their gas / ore.
Final comments
I'd recommend this for low sec only, preferably in areas with stations nearby.
I've estimated the isk/hr for this ship to be 40M-70M per hour, depending on which region you're in (some regional cyto gas and salvage are worth more than others). If you choose to run a pure PVE fit (i.e. gas harvesters in high slots, relic/data analysers in mid), and refit for combat if you see someone interesting, you can push for 70M-90M per hour. Cherry-pick relic sites and hack the Remains cans only. Skip all data sites unless its a Covert Research Facility.
