Code 2 WP plugins (front & back end) for portfolio & examples of good practices with search engines

I'm looking for someone develop two Wordpress plugins including a good looking visual design, it needs to be implemented well to The Ark theme, so design will match. Please check these 2 links first so you will have a better idea how this system would look like, they are similar like my idea: [login to view URL] [login to view URL] In case of the 1st plugin, it should be a database for examples of good practices. They need to be displayed on one of the pages. Each example has a title of the project, links to social networks (FB, Twitter, Linkedin), basic info in indents, short description of the case, a picture and up to 5 PDF files in English language and another PDF in a selected, custom local language. An important part is a search engine just like on the 2nd link above. It should have a custom search text box as well as 8 dropdown menus with 5 options each for filtering. All the filter data is text or numbers in ranges. Search should be intuitive and user friendly. You should code the plugin it in a way that it will be also upgrade-able in the future in the way that users will be able to add examples of good practices as well (so user registrations, logins, profiles, editor etc.). But as said, this will not be the case for now, just keep it in your mind. For now, I just need a full administration in admin back-end, so a complete editor to view, edit, publish, publish/unpublish examples etc. The second plugin is similar, but it should already support user registrations, login and their own editor of the examples of good practices, so they can always edit/delete it, however administrators would have to approve each edit (moderation). In other words, there should be a 3-stage user system: 1st visitor, 2nd user which can edit his own content and 3rd administrators. User names should be public – displayed at their content. The amount of data would be about the same as in the 1st plugin, there would just be a different type of data, so to name them: country, category, contact info, social networks, skills etc. So more personal thigs. The search engine should be similar as in the 1st plugin but with less filters. The first plugin would be in English, but the 2nd one should be translated into 5 languages at front-end, Users could choose the language of their profile/content. I would insert translations on my own, but you need to provide me that option in back-end. I will use WPML on the website to translate it to other languages, so the best would be if the plugins would also switch their language based on WPML translation. In other words – plugins should be WPML compatible, but not necessary that I translate it with the WPML, we can use other ways as well Some display sorting of the search results would be also needed (like sort by date of entry, sort by name etc.). The results listed could be also just partial and then each entry would have “Read more” button, which would expand it. Both plugins are completely separated; they are not linked to each other. Please do not send me placeholder bids. Write me down complete, realistic price and how long do you need to finish both plugins including the implementation on the WP website. I also expect that you send me your references. I expect high quality, professional work.
