Design a Authorize.net Wordpress Plugin

Hi I need a wordpress plugin developed. It will be a plugin that people can easily use their [login to view URL] account in their wordpress website/blog the plugin should do everything this plugin does: [[login to view URL]][1] please watch video. upon winning bidder i will get them the above plugin to evaluate. this plugin u build should be better, more user friendly, and have more features, which will be listed in the advance detailed section below. there will be a free version of this plugin that just does donations, and the full vs will be a paid version with lic and keys. (need the developer to set us up with lic/keys) please read full details in advanced section below. ## Deliverables it should be able to do subscription/recurring payments as well as one time payments. NO MEMBERWING FEATURES - that is the only feature i do not want. i would like this plugin to have the ability to be under each post, so that the user can add in a price, either one time payment, or recurring payments, OR they could add options with a drop down menu: such as: XXL XL L M SM XS there should be recurring and one time payment options for all this. a donation short code for pages, and posts, as well as sidebar widget for donations, where people can put in whatever amount they want to donate. when the user updates/publishes the post, there would be options below the page or poast to add a descriptoin and amount, there would automatically be buttons inserted in post for what they just defined below the power. an example would be very simular to eshop plugin, but eshop plugin has NO options for recurring payments. i do not want paypal intrigration, just authorize.net. user should be able to just enter: email address associated with their [login to view URL] acct API Login ID Transaction Key MD5-hash phrase and after they add that info the plugin should be good to go. the plugin needs to be [login to view URL] compatible up to latest vs. and compliant to <[login to view URL]> there should be a css file where users can edit how the buttons look. would be great if there could be a graphic section in the plugin settings where they can user a visual editor to choose the color they want. it needs to be designed with licsence and keys as we are going to charge for this plugin. the plugin needs to be able to be automatically installed thru the back end of wordpress just like any other plugin, where its activated. developer will need to be ready to support the plugin and help clients in a forum for the first 30 days, and be ready to make sure the plugin will work with future upgrades of wordpress. please let us know how much you would charge for the additional support and we will consider that when accepting bids. reminder, short codes for pages and posts -for example: when a user setups a reoccuring payment for $25 a month, the plugin will give them a short code for that reoccuring payment. reminder: free vs - just donations with teh ability to upgrade to full. full vs-should have all the features above.
