Convert Joomla website on Iphone and Android

We have a joomla website with about 500 articles. There is a forum (Kunena). There are google maps with placemarks (webmapplus). The goal is to create a better website for Iphone and Android. Users could select NORMAL or MOBILE website. We already installed "Joomla mobile" but Kunena is not nice, we want much more, new menus to simplify tasks, etc. Our website is Isaan "do.t" C.om. Can you read it? :) If we can integrate google maps, great. If you can also integrate position of the phone, with google maps telling you what is around you using our placemarks, MUCH BETTER (But I think this is complicated or expensive). We want to do the simpliest, easiest but good looking website on a phone, with a small budget. Not sure how much it could cost. We have news in RSS or with twitter on frontpage. Maybe it has to be transformed to look quickier on a phone. Please send us similar example you did on Iphone and ANdroid, we will check. Delay is 1 to 2 weeks to complete the project. No hurry. The cheapest is the best, but it must look good too. We also use JOOMFISH with Thai and English. So, it should be easy to change between Thai and ENglish, normal or mobile, access to forum or news. I am not sure if it is a project higher than 250$... just bet, show us what you did. If you have no review, forget that project.
