Developing Compilable WebCrawler written in Java

Hello there, I have a java project which I want to develop for my report. The project is simple WebCrawler with no interface included. I have managed to finish most of the parts. All I want is optimisation and changing some features of the project. The reason I want to hire a person is, I have no time to optimise this project for the following 1-3 months. What I want is; 1st) The database kept on text file. I want to change it into MySQL database to make it more efficient and easy to understand. 2nd) Threads. I am using threads but I want them to work more efficient than current version. What threads will be doing is, they will be assigning to one job only ( for example; Start crawling: [login to view URL], dont pick any other job like [login to view URL], [login to view URL] until it finishes the [login to view URL] ). The trick point is, when the thread is crawling the links in [login to view URL], it should check the links in the another database ( pool DB for links ) whether it exists or not. If it exists, it shouldnt add it into database to prevent extra work and prevent repeated data. 3rd) I want this code to run properly. It doesn't work efficient currently there are some stucking points and other stuff. I have been using several testing tools but some internal code should be corrected. 4th) I am using [login to view URL] file, update it with the never version. ( Pretty simple.. ) ---- Finally; I will be giving the whole source-code to you. You will have plenty of time to understand and achieve the goals stated above. As I am giving the source code to you, you would keep it and use it in the future, so please consider this before offering a price. The codes, other stuff and information will be updated as soon as I hire the professional. The due date is : May 20th 2014 (±5 days) Thanks in advance!
