Charity donation solution (not online store)

Hi, This is a smaller project for a developer with expert skills in Wordpress, HTML, PHP, CSS and online donation/charity payment solutions. The project scope is estimated to no longer than 7–8 efficient hours for fast pay. Notice that this project is not about building an online store. It is not for selling products and hence is not complex in that way. Do have this in mind when reading the rest of the description and when placing your bid. It is a must that you are meticulous, so please pay attention to the whole of this description and its details, while bringing your own smarts and common sense into this project. To think of in general: Make appropriate implementation and changes in current Wordpress theme so that nothing will be overwritten when updating the theme itself. Project description: (1) Find the best possible solution for donations globally (or as global as feasible). To consider: (a) Use services with lowest possible fees/free services for the solution to work. (b) Has to work from mobile device and desktop. (c) Has to be user friendly and light with as few clicks, input fields and steps as possible from CTA to donation/payment. Visually simplified for visitors. A maximum of three steps for the visitor, for instance: (c1) Click on CTA. (c2) Fill in short donation form with choice of payment/donation. (c3) Confirmation of donation. Smart solution for making a hassle-free experience for donor with app-like transitions between steps. (d) Has to work with credit cards, bank accounts and/or smarter options, for instance payment on mobile device added to mobile subscription bill. You should know how for instance Paypal, Stripe, TransferWise, Google Wallet etcetera work at a technical level. (e) Micro donations should be possible (any amount). (f) Bring your own smarts and common sense into the solution. (2) Implement the solution beautifully to our Wordpress website. To consider: (a) The donation CTA should be able to be placed in the sidebar (typically in a widget), in chosen post title(s), responsive menu header and within in posts. (b) Eventual form, if smartly integrated, may be visible directly to reduce clicks, or may appear in the main content/post area or as an overlay popping up when clicking CTA. No other design/layout must be affected unless for the smarter. If helpful we use Yellow Pencil. When awarded this project, you will receive necessary user details. Upon project start you will need to communicate what (free or low fee) services we should sign up for. We currently are signed up for Paypal Looking forward, Team Cross
