i want to start a e-shop based on [login to view URL] i bought that code but i need to add new features, i attached a file open it you can see all the modifications required, open [login to view URL] cos it's the root page. Look at: [login to view URL] a really clear guide of code for developers, you have everything there, look at tools used and needed to do and to extent the code, a complete documentation can be found there if you have experience with the tools used it's easy to extend the code full documentation of the tools and code used to develop the java shop, most part of the new code to add are based in copy exactly schemes done or adding fields to existing schemes i'm looking for an experienced programmer with the requeriments like you can read at this project i want to start a shop with this software and i'll need more modifications after this project is done and if a lot of changes are required in the next months i'll offer a monthly contract, i selected a budget between 300-1500$ for this part, after the code is done i'll need to check it to be able to configure the shop(new temaplate shop system) and to connect to the shop 2 external plugins and a payment gateway,this second part of the project doesn´t require to develop a lot of code just to fit external code with the shop, some of these external plugins are php based it's required to have some experience connecting scripts in diffenent languages using xml, for this second part of the project you can bid until 500$, first bid: 300-1500$ after the code is done we need to connect to other scripts and built a new template setup: second bid: until 500$(send me a private message with your second bid). I would like to find a programmer with experience with tomcat/apache/mysql security and java encrytpion to try to do the shop more secure and also it's required to connect the shop with php scripts and payment gateway.
