Hi. its not that easy to jump right in to things like that. You really need to have a basic idea first before jumping into advanced modding. Here is a good guide that will help you get started. It is outdated to a certain extent but will get a basic idea of what it takes.

If you can get a simple object into the game then a Modder might help. With absolutlry no experience at all modding could take a few days, weeks or longer to get it down. We can help with question like where a folder goes or whats the best way to texture objects. We need some kind of Experience lvl before most modders will volunteer to help. Hope this helps.

Ive been looking at that one, and using a YT series that uses it. Still working on setting up Blender.
