Hi all,

Im not sure this fits here, but im in need of somebody who can help me a bit with my website.
SOme things are just not working anymore – any kind of payment – and some buttons dont work or are shown double.
It would be nice if somebody with good coding skills can help me fix these problems, as i cant get past them.
Im willing to offer a bit of money for any help.

Please let me know if you can help me and im sure we can work something out. Ill show you the exact problem then ??

Thanks!
