Gloucestershire's John Bracewell says he wants to keep Chris Taylor and Hamish Marshall but financial restrictions might hinder the deals.
Both batsman are out of contract at the end of the season.
"We hope to keep him [Taylor] and Hamish but I don't control the purse strings," director of cricket Bracewell told BBC Gloucestershire.
"There is a priority and that is to establish our ambition as a club and as an international ground."
He added: "This is in order to finance cricketers in a very competitive market."
The club have submitted plans to the council to redevelop their Nevile Road ground in Bristol and if the proposed renovation goes ahead, it could mean a tighter player budget in the future.
"It is frustrating but I know what's there, it's not as though it's a surprise," added Bracewell.
"We've got two cricketers we want to keep and it's just reality and you've got to deal with reality."
Taylor spoke out about his future last month and agreed that ground developments had halted any talks about a possible new deal.
He has been in impressive form in recent weeks and his final day century helped Gloucestershire earn a draw against Essex in their County Championship clash, a performance which Bracewell believes will stand out to the club's directors.
"There's nothing like a little bit of pressure in your last contracted season to turn it on for the accountants," he added.
