First, Your site is very easy to replicate. Someone can build a site for less than $50 can achieve what you are offering. You can't even say that "you will get a review from high PR site" since your site has no PR. Your site is not old enough too to have the authority.
Second, someone can easily get clients for the service you are offering through some freelancing site (e.g. fiverr). why would i spend a lot of money by buying your site if i can get the clients for free.
That being said, your reserve is still high. but flippa has a lot of noobs that want's to gt their feet wet, so you might hook up someone for that price.
My suggestion is if you want to buy the homepage feature, buy it 24 hours before the ending of your auction. The average time you will be featured in homepage is 24 hours and this will also compliment you being feature in the soon to end listing.
Thank you So Much For All The Time You Spended On This Issue! I Will Purchase The Homepage Upgrade as you said and I will sale it for any price whether is may be low or high as I need some cash!
