Hi,
It's a little hard to estimate without knowing the website and the scope of data. Also, you indicated Java as the required skill, but I would like to know for sure if this is the environment you require.
I can do that in Perl, PHP, Java, Groovy, Python - and if you require some other language, please clarify, I might be able to do it as well, those are just the most popular for this kind of job.
Regarding my qualifications, I have 20+ years of experience with Unix/Linux as well as Windows; including system administration and programming in these environments using C, Java, SQL, Perl, PHP, shell, and other niche languages.
Check my profile - the reviews and completion rate. I always finish if I start a job.
So, please contact me and provide more details, so I can review the project and properly estimate. I hope for a very fruitful cooperation.
Best Regards,
Marek Bukowy
