Develope multithread python crawler -- 2

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!
