It was revealed last week that the Hammers had put in a ?9million bid and that Jarvis had expressed his desire to leave Molineux.
He is keen to step back up into the Premier League after suffering relegation out of the top-flight last season.
West Ham are ready to offer him a route back to the big time and are prepared to dig deep in order to secure his services.
The Hammers have, however, been left frustrated in their efforts to take the England international to Upton Park.
Wolves are reluctant to part with any of their key men and continue to fend off mounting interest from afar.
Sunderland continue to track Steven Fletcher, but have yet to meet the Scotland international's valuation.
Wolves are also prepared to stand firm on Jarvis and hold out for the best possible price, or keep him on their books.
