    I need to build a reliable, well-structured lead list and I already know exactly what it should contain. The task is to extract contact information—email addresses, phone numbers and full mailing addresses—from three sources: company and organisation websites, their public social-media profiles, and well-known online directories. I expect the data to be gathered with a solid scraping workflow (Python, Scrapy, BeautifulSoup, Selenium or an equivalent stack is fine) and then verified so that bounced emails and dead numbers are kept to an absolute minimum. Deliverables • One CSV or Excel file with separate columns for name, company, job title, email, phone, street address, city, state, ZIP/postcode, country, source URL and date collected. • No duplicates; every...

    I need to obtain hard-to-reach details—specifically the IP address, associated phone number, and any location-related information—linked to one particular Telegram account.

    I want to turn my existing catalogues and knowledge base into smart, intuitive WhatsApp agents. Whether you prefer OpenAI’s Agent Builder or an n8n flow is up to you—as long as the final bots handle automation for user support and information dissemination flawlessly. Users should be able to ask a question, receive the right document or answer instantly, and feel as if they are speaking with a well-trained human agent. Alongside the chat experience, I need an end-to-end AI pipeline that automatically extracts raw data from the web, aggregates and cleans it, performs analysis, and then publishes clear visualisations—including map views—so insights are always one step away. I’m comfortable with tools such as Python, Pandas, LangChain, Node, SQL, Power BI, Table...

    For an upcoming market research study, I need a fully-automated workflow that gathers and enriches data from well over 500 LinkedIn profiles. The automation should locate the profiles that match criteria I will provide, pull the key public details, then append reliable off-platform contact information so I can reach those professionals directly.

    I’m interested in buying an existing dataset you’ve already scraped from TruePeopleSearch. What I specifically need is the contact information section—phone numbers for sure, and any email addresses or other direct lines you may have captured at the same time. I don’t need the address history or relatives/associates fields, so feel free to leave those out if they’re present. This is not a fresh scrape request; I only want data that you currently have on hand. Anything compiled within roughly the last twelve months is perfect, but older archives could still be useful if they’re large and well-structured. I’m flexible on format: CSV, Excel, or JSON all work. Just let me know which one your files are in, when the data was pulled, and roughly how man...
