There are a toe of indexer companies out there. Instant Link Indexer is probably the best, used it myself and it does work.

However, be careful when dealing with a business client who wants this type of "shady stuff" done. Payment upfront, define exactly what you're actually providing and make sure your prices allow you to carry out the work with a healthy profit.

Reason why I mention this? It sounds like a real sketchy job and my experience is sketchy job = sketchy client.

Be careful!
