Mybb Forum cutomization and integration with wordpres needed

Hi, I have one wordpress site with simplepress forum in it. Now i want to have a different more powerful forum software in it. I am planning to have mybb forum this time but currently looking someone who could customize it according to my website theme. What you need to do: [login to view URL] MyBB forum should looks exactly like my website : this includes putting header and footer of main wordpress site into MyBB forum. 2.I want to have rating system in my forum , where users can rate threads.. Currently MyBB offers this rating feature but i want to change it to thumb up and Down feature: In this user who likes the thread can thumbs up the post and those who don't can thumb down and final rating will come on the basis of thumbs. 3. I want to have full featured point system in my forum , where users will get some points of posting content. There is already one plugin "new point system" available but little tweaking needs to be done to suit my needs. If you can do all the above things then please let me know the price..also if you are expert in any other forum software..then also do let me know. I don't have problem in switching to any other software like vbulleting,punbb etc.
