Argyle's frontline has been weakened by the absence of Belgium striker Emile Mpenza through injury, and Stapleton claims Sturrock is free to bring in a replacement, with money no object.
"We are all in this together," Stapleton told the club's official website.
"We've said to the manager that, if he wants anybody else in, we can help him. We don't have to get rid of anybody before bringing anyone in.
"If we need a striker - if we need anyone - I've told Paul he can go and get him, irrespective of the money. If he wants someone else he can go and get him. He does not need to worry about getting people out. If he needs a bit of freshening up we will support him.
"At the end of the day it's important that Plymouth Argyle stays in the top 40 teams in the country."
