SAP ABAP ALV report with Edit selective fields, Save, Delete rows, Change logs display in OOPS concept -- 2

Hi, I am looking for someone who can deliver an ABAP report, that will display an ALV (preferring SALV) with some columns in display and others in edit mode. The fields will have values ranging from text, currency, quantity and numbers. Functionalities include loading the program values referring from couple of tables, on saving the values to be refreshed, row level deletion, enabling ALV option to download as excel. Also, change log history in the same screen or popup by taking inputs through selection screen. OOPS with local classes should be used throughout and all report event's (like at selection screen etc) should call methods to perform the operations. This is time critical and the entire code SHOULD be delivered within 3 or 4 days of acceptance. If not, please avoid bidding. Expecting bids around $350. Thanks.
