Bugs to be fixed on web site marketplace script

I have a web site marketplace script installed on my web site that has a few minor bugs that I am wanting to get fixed. If you PM me, I will let you know the url. First bug: When submitting a new site to sell, after clicking submit at the end, it just refreshes the page. Sometimes it will post the auction but sometimes it will not. I would like it to goto a page that says Your auction has successfully been listed in the marketplace. Along with another message attached to it underneath. Then I would like it to show the URL to their listing where they can check it out. Second Bug: I would like to change the credits that the user gets when first signing up. I could not find this anywhere in the code, but maybe someone skilled can. Right now it gives new users 50 credits. I would like to change this amount to 14. and learn what file i have to go in to change this later on. Third bug: The phone verification system has error in it that i noticed. I tried verifying my account, the admin, and it did not work. But now on all the accounts, it shows that its awaiting the pin that was suppose to come in. So maybe something in the code got crossed some how. I would like this to be looked into and fixed and working with my [login to view URL] account (it is already coded for it, just dont know how to configure it in) That is about it right now. Whoever takes on this project will be hired for future projects in new features to the web site and any other bug fixes.
