Lead generation in India

We require a lead generator once we establish a relationship then we would like this to develop long term. We would require a maximum of 20 leads from India per search. Basically the way this would work I currently have one client who wants details of open pit (or open cast) mining contractors From India I then need to provide the client with up to 25 open pit mining operators and return each job in excel format. Each job is different in terms of the type of Indian contacts they are looking for. The information that I need on each potential partner would be Company Name Address Telephone Fax Web site address Email general The name of at least one contact person i.e purchasing manager, general manager,director (someone who would make purchase decisions) any contact name is better than none. Email of contact person. Year Established Turnover The skills that are needed to do this job are a Native speaker and a good understanding of English, being good at researching via the internet etc., good business sense, data entry(but minimal). At first it will take a while to do this quickly but normally after have 3 / 4 companies everything started to click, So this job requires you to fill in the gaps of missing data in the companies we provide to you and secondly finding new companies in India that match are searching requirements. We would normally pay per lead generated. If you could consider if this is something that you think you can do, you might want to do a quick search to see how workable it is for you and therefore what you would charge for a job like this? We would normally require the job returned in 7 days very rarely is it more urgent. We also some requirements for pure data entry positions as well, so if this is something you can do then let me know I look forward to your response.
