Recommended backlink indexing/crawling/pushing service?

Hey folks! I'm interested in a link processing service to help improve the crawl speed and impact of backlinks faster.

I was recommended to try out linkprocessor.com, but I wanted to know if you all have a recommendation for a similar service or if anyone has used that service and would recommend it. As I am not familiar with them, I value recommendations made here more than other places. I'm told these services can indeed help get pages indexed and positioned better, but looking to separate fact from fiction and recommended from junk.

Any insights and advice as it regards these sorts of services would be greatly appreciated as always.
