Friends of 17-year-old Georgia Williams are hoping to raise more than £1,000 for a permanent memorial to the teenager.
More than £600 has already been raised for a memorial bench, which they hope can be placed in Wellington, Telford, Shropshire.
On the indiegogo fundraising page, organiser Steve Millington, wrote: "17 year old Georgia was loved by many, and her story touched the heart of the nation.
"We are looking at erecting a memorial bench in her memory and to celebrate her wonderful life. This will be something that everyone that cared for her can be proud of.
"With your help, we can immortalise her memory."
He said they would be discussing plans for the bench and its location with the Telford and Wrekin Council and register office. Any excess money will be donated to a relevant charity.
Georgia is believed to have been killed after she disappeared from her home in Wellington last Sunday evening.
Yesterday her parents Stephen and Lynette Williams were joined by more than 100 family, friends and well-wishers at a vigil at AFC Telford United's ground.
Paying tribute to his daughter, Mr Williams, a detective constable with West Mercia Police, said: "Georgia, you were a great girl. Thank you for being in my life. God bless you."
Later he said: "Today is a day for Georgia and for us to meet her friends and for us all to celebrate her life."
Boyfriend Matthew Bird, 19, said: "Today has just been outstanding. I can't explain to you how perfect it has been and, take away my feelings, the support everyone has given to her friends and family is phenomenal. I know she would be so proud."
Numerous bunches of flowers, football scarves and messages were left on the north stand of the stadium, where Georgia worked on match days.
Club chairman Lee Carter said: "It's a very sombre day, but I think people being able to come here has allowed them to express their grief and sorrow."
He added: "She was a lovely girl. Very polite and well-mannered. Bright, bubbly and really did make a massive impact on anyone she came in contact with. She will be sorely missed."
Jamie Reynolds, 22, was arrested in Glasgow city centre on Wednesday and charged with murder on Friday after a body was found in woodland near Wrexham, North Wales.
West Mercia Police are yet to formally identify the body, which was found off the Nant-y-Garth pass, but have said they believe it to be Georgia.
Reynolds appeared before magistrates in Telford yesterday accused of murdering Georgia last Sunday. He was remanded into custody to appear at Stafford Crown Court on Tuesday.
Detectives investigating the murder have appealed for the public's help to find a black leather jacket Georgia was thought to be wearing on the day she went missing along with a leather spotty satchel; a pink, flowered make-up bag
and her Samsung Galaxy Y mobile phone.
Detective Superintendent Adrian McGee, from West Mercia Police, said: "The support the public and the media have given to our investigation so far has been fantastic, but we need to ask for their help once more as we try to find these items.
"If anyone is aware of their whereabouts or comes across any suspicious items, particularly in the area between Oswestry, Wrexham and Ruthin in north Shropshire and Denbighshire, then please get in touch."
Anyone with information is asked to contact West Mercia Police on 101.
