And beyond that there could be a money-spinning tie against a Premier League or Championship club, which could feasibly bring in hundreds of thousands of pounds.
Lincoln made around £18,000 for winning the tie against the Saddlers and the cash is vital because of the budget reductions in each of the last two seasons following relegation from the Football League.
Dorrian added: "This year was probably going to be even more difficult than last season in financial terms, so any extra income we can bring in this season will be a massive boost."
But Dorrian said the team's performance and achievement in beating a team two leagues above them for the first time in their FA Cup history even outshines the crucial off-field implications.
"It was an absolutely wonderful evening," Dorrian added.
"We felt that it was something that had been coming for a while now. We felt we were beginning to sort ourselves out on the field and off the field.
"The future's bright and, after last night's performance, who knows where we can go.
"I have to say I haven't had many highlights since I have been chairman but certainly last night made everything worthwhile.
"I think we are very slowly turning the corner. We have gone nine games unbeaten in league and cup and the team itself is a fantastic unit.
"Everyone plays for each other, morale and team spirit is off the Richter scale.

After several difficult years, including relegation from the Football League, this will do much to raise morale and make all believe there can be a brighter future. The win was City's first in the FA Cup against a team two leagues above them and extended their unbeaten run to nine matches. For me though, the most significant thing was that players, management, fans and the board were united as one. It hasn't been like that for some time and for the club to go forward that is how it will have to remain.
