Improve a humble application I've done without being a programmer

I need a person to evaluate a software I made ??taking pieces of code, for particular purposes of quality management systems for online access, and see if it is worth improving some aspects, professionally (I'm not a programmer, and also I have no time). I mean to fix bugs encoding (utf8, iso 8859-1), to improve the template as it is seedy; improve menus, make some ajax events like edit in place ... etc. For these purposes, it is good to know something of quality management, but not required. The person who help with this, will share sales rights (50% or up, if it could be sold). Currently, i´m using the aplication to work with a few clients, but I use it as a personal tool. I have not sold the software to them. If you could be interested, i´ll transfer the archives, not before the contractual relationship were clear. I dont give a link, due to a possible hack action. I will send the aplication with two or three modules installed, to those persons interested. And I beg you please excuse the ugliness and the inability of coding, but you may know that I am not a coder.. ¡¡Thanks!! From Spain
