If your squad is deep enough, arrange a friendly against a team with much lower rep. Arrange it for the Monday, stick one/two of your strikers&hopefully they should score a few. The 5 days should be enough for them to recover for the next game.
At League 2 level, the standout name that I can call on from my minimal LLM experience is Febian Brandy, a class above everyone else. Nicola Ventola is also a free agent that I bought for Crewe and had great success with. Basically look through the Free Agents list, maybe download a shortlist from here with good free agents and filter out the decent strikers
The only problem you might have as Stevenage is his wage demands... As far as I remember he ended up getting in excess of 2k p/w with me at Crewe, pricey but worth it although sometimes his finishing is rather frustrating.
