URGENT: Add donation page in existing site

Simple & Urgent Project. Current site under Wordpress. I want to add a donation page where web user select one off donationOR recurring donation. Then user select amount (or enter their amount) then add their particulars info & make pay, all in 1 page. Need this done urgently & it would take 1/2 day todo this (or less). U can use woocomerce for this. But need to wait awhile as payment gateway has yet to be activated. U need to link with payment gateway as well.
