Sorry Sarkar, a bit late with my review:
Sarkar is very easy to work with. He confirmed the work before beginning and stayed in communication as it was being done. The work was delivered on time as he had described.
Report: Very easy to read excel spreadsheet. I've received txt reports and even PM reports recently for some services, not very easy to work with. Sarkar's report is delivered in a tabbed xls with live links listed by type.
Links: I checked a lot of them, more than a few dozen, and they were all there, every one. If you know Sarkar's work you know he focuses on quality, not just quantity. These aren't really spammy links, they're mostly well placed and will most likely stick for the long term.
SERPs: Sarkar's work was focused on a very competitive kw phrase in a very competitive overall niche. Site is established, several years old, good on-site SEO. I'm up against a few multimillion dollar ad budget competitors. This link package was not the only work I had recently done to the site for this keyword but it definitely was a major part of getting it into the top 30 from more or less no where.
Price: Well worth it for the service being provided. IMO the few bucks you might save getting these links from different providers are more than worth spending for since you're getting everything from one place and you know Sarkar's work is good.
I might also add that OP's work is not blasted out all at once like some other services. Not saying big link blasts of any kind is bad necessarily, not at all, but I still err on the side of caution sometimes and this kind of time-release mixed link package is good for that.
Overall, highly recommended.
