I have a MySQL DB with website urls and serverpath of pictures it it. I am looking for a guy who can program the following multithread python crawler: - Each website url that was not checked yet, is visited - It will be checked whether the source text of the website still contains the picture URL - if this is the case, a "YES" will be added to the column "online". If not, a "NO" will be added to the DB column. - If the picture url is still online, it will be checked on the website url whether there is a certain variable text string (implemented in DB) on the website (important: on the website, not within the source text to exclude alter tags, etc.). If yes, a "named" will be added to the column "photographer". If not, a "NO" will be added to the column. - Proxies need to be used for that project (available here) - I want to have the option to set a delay time between crawling a website url of the same domain. Looking forward to your bids!

I Python developer with many years of experience that's why I'm sure you'll be impressed with my work. I can create such program for you in 2-3 days and I can offer you best price here. The program will read URLs from DB and check is there picture URL on this URL. If yes the crawler will make additional check (searching some text on the page). To start I need some real data / samples so I can check everything. Also I need milestone payment from you. You'll release it after you check everything on your side so nothing to worry about for you. The crawler will read list of proxies from the text file. It will delay for the given time after each request. And you can set number of thread in it. Thanks. Roman

Hi. Yes, we can develop a multithreaded crawler for you. Few questions so far: 1. On which OS will you run the script? 2. Can I have access to your MySQL DB so that I cold test it on real data? 3. How big is the DB? 4. How many proxies you want to use ? This are the questions so far. Waiting for details.

Hey there, It's usually best to use an off-the-shelf crawler for Python. But, custom with proxies no problem. I can do a follow on and turn this into a django web service too if needed. Based in Toronto.

Hallo, ich bin Softwareentwickler und aktuell auch Mathematik-Student. Ich habe die letzten Jahre fast ausschließlich mit Python in der Softwareentwicklung gearbeitet. Webentwicklung ist allerdings Neuland für mich. Die Aufgabe scheint mir aber für den Einstieg gut machbar zu sein und wenn wir uns nach dem Auktionsende nochmal über Details unterhalten, sollte ich relativ schnell das gewünschte Skript fertigstellen. freundliche Grüße

An example of a crawler I made is one that logged into my colleges student directory, and make searches on each permutation of letters for initials. Took the data that you got from the searches (first name, last name, major, minor, classification, and email) and built a database of all currently enrolled students. Was a little tricky due to security requirements of site and having to limit requests without getting an error. This is just the fanciest crawler I can think of at the moment that I've made. BTW, I have no idea what kind of milestones to put.
