Decode eval base64 files

Hello there,

I have 5 ".php" files that I needed decrypted/decoded, they seem to be eval base64.

I will send the 5 files once I have picked the right person.

This is a sample of the beginning of the code:

<? $OOO000000=urldecode('%66%67%36%73%62%65%68%70%72%61%34%63%6f%5f%74%6e%64');$OOO0000O0=$OOO000000{4}.$OOO000000{9}.$OOO000000{3}.$OOO000000{5};$OOO0000O0.=$OOO000000{2}.$OOO000000{10}.$OOO000000{13}.$OOO000000{16};$OOO0000O0.=$OOO0000O0{3}.$OOO000000{11}.$OOO000000{12}.$OOO0000O0{7}.$OOO000000{5};$OOO000O00=$OOO000000{0}.$OOO000000{12}.$OOO000000{7}.$OOO000000{5}.$OOO000000{15};$O0O000O00=$OOO000000{0}.$OOO000000{1}.$OOO000000{5}.$OOO000000{14};$O0O000O0O=$O0O000O00.$OOO000000{11};$O0O000O00=$O0O000O00.$OOO000000{3};$O0O00OO00=$OOO000000{0}.$OOO000000{8}.$OOO000000{5}.$OOO000000{9}.$OOO000000{16};$OOO00000O=$OOO000000{3}.$OOO000000{14}.$OOO000000{8}.$OOO000000{14}.$OOO000000{8};$OOO0O0O00=__FILE__;$OO00O0000=0x8d8;eval($OOO0000O0('JE8wMDBPME8wMD0..............='));return;?>FHwysqcygBkr9..............

I have some of the code hidden above with the "..............", but this is just so you know what type of code you will have to decrypt, as I can't paste all the sources here.

I was able to decrypt some of it, mostly the beginning, but I got stuck later.

Only serious professional please.

Thank you!
