Programming An Online Shop For vBulletin

[Wordplay]

i would like to put together an online shop, that works together with the vbulletin software. as i have described here:

https://vborg.vbsupport.ru/showthread.php?t=234190

considering i have practically no php knowledge except for how it works, and how we used to implement hacks/mods into older vb versions.

how long would it take me to learn how to write this mod myself? and could somebody supply me with a link that would help me learn to program this mod for my vbulletin 4 forum. i think i'll find somebody else to write it for me, but i'd love to be able to edit, change, and enhance it myself later on, so i really need to step up my php knowledge. and if i can't find anybody to write it for me, i'll have no choice but to do it myself anyways.
