Councilwoman Jan Perry, who is acting mayor while Antonio Villaraigosa is out of town, has asked for donations, but so far the city hasn't gotten any.
A Web site was posted Tuesday seeking donations to cover the costs, estimated at between $1.5 million and $4 million, according to Matt Szabo, a spokesman for Mayor Antonio Villaraigosa.
The Web page reads: "Help the City of Angels provide the extraordinary public safety resources required to give Michael the safe, orderly and respectful memorial he deserves." The site is linked to a PayPal account where donors can make tax- deductible contributions.
Those who wish to donate can make the check out to the city of Los Angeles.
AEG Live, the promoter for Jackson's now-canceled London shows, has not committed any money to cover the city's bill for the Jackson memorial.
