I think we had a thread on this recently called "how do you flippers make any money". Essentially you need to start with a desirable, higher quality bike at a low price in a market that will pay enough for your time and material.
Paint looks great. Alloy wheels, nice stronglight crankset. The downside is of course the claw and other markers of a lower end bike.
If that were my project it would get a complete disassembly and reassemble with new tires, hoods, saddle, bar tape, brake pads, chain, cables and housings and bearings.
However if your market isnt hot to trot then there is no sense spending a day doing a bunch of free work for someone else unless you really happen to like doing it and feel some kind of satisfaction putting another bike on the road. Otherwise the other options are to clean it up and list as is or disassemble into components. However lower end components have limited resale value.
