oscommerce charity donation project

I would like to have a fresh oscommerce 2.3.4 install modified so that the admin or store owner can use the product info page to ask for donations and a thermometer will appear showing the progress. Demo: [login to view URL] [login to view URL] [login to view URL] The work required is for store owner to make Donation products. Customers cannot upload nor create Donation products. ONE When creating products in admin, an option for "donation product" and other input fields will be present: Donation Target: INPUT FIELD Target Start Date: INPUT FIELD Target End Date: INPUT FIELD Minimum Donation Allowed: INPUT FIELD Maximum Donation Allowed: INPUT FIELD Maximum Number of Donors Allowed: INPUT FIELD Allow Excess Donations: Y/N DROPFIELD Add Gift Aid to target amount? Y/N DROPFIELD TWO The thermometer must be HTML/CSS based, it cannot be one created as an image on the fly. It can show all information from create product page (start/expiry if selected as well as target amount) THREE There will be an input field where customers can enter the amount they want to donation. If a dropfield can be added with minimum to maximum amounts then that will be considered too. Usual oscommerce product/attributes apply as well. FOUR There will be an area of the product info page where donors can leave a message, it will also show the amount donated and if gift aid was selected by the donor. Donors can remain anonymous if they [login to view URL] will be separate comment boxes for each item/donation at checkout and each box will have limited characters space. There will be a single gift aid checkbox at checkout. FIVE If the gift aid checkbox is ticked by a donor when checking out then various things could happen. Here is an example of someone donating £100. The customer will only pay £100 regardless of checking the box or not. Currently gift aid is 25% of amount being donated. - if the admin has selected "yes" to "add gift aid to target amount" and customer selects gift aid then the gift aid amount will be added to thermometer graphic. It will show in customer comments too - if the admin has selected "no" to "add gift aid to target amount" and customer selects gift aid then the amount will NOT be added to thermometer graphic. It will show in customer comments that gift aid was selected If you have any questions please get back to me :) Sensible bids please
