Looking for experienced developer in wordpress woocommerce Auction + cron events

Need to fix few things in the existing website, This website related to wordpress + woocommerce + woocommerce auction plugin + proxy option + cron events Please look into the website [login to view URL] Its a wordpress woocomerce Auction site, website almost done. Proxy Auction option too almost done but not working in the required workflow - its pending. Google it "Proxy Auction" for more info about it. Working Logic = When Customer start clicking "Bid Now" button - 10rs will add to the current bid value and 1 bid (points) reduced from his account(customer will already purchased bid to is account - its like points / wallet money each click will reduce a bid / point ). Proxy bid logic:- If a product value is = 5000 rs admin set starting price much lower around = 500 rs if he sell product less then = 3500 rs then it'll be loss (Minimum proxy Bid Value - MPBV) and No user bid the product after around 600 rs means company then need to give the product to the customer for 600rs and it'll be heavy loss for the company So a automated traffic / proxy users will increase the product price till 3500 rs There will be a set of usernames will update while running a cron job --> its already done the proxy need to place bid at last 2 seconds or 1 seconds again the timer will automatically increased to 10 or 13 seconds again the proxy will place the bit at last 2 or 1 seconds again the timer will increased to 10 or 13 seconds it'll continue till the minimum proxy amount reached Requirement Now we're having proxy bidding option which it'll continuously place bid for every 8 seconds but we need it to place only after 10 seconds. Refer: last point 1. Identify last three or two seconds of the timer 2. Increase the timer to 10 seconds 3. Auto update of current bidding value and winner name on live auction without page refresh. (Right now ajax option working for manual bidding and for proxy option its not working) 4. This last three steps will continue till meeting MPBV 5. Our previous developer done something and its working for live auction page not working for single product page (timer increasing to 13 seconds while reaching 3 seconds and auto update proxy amount +10rs its adding) but he's not able to complete this issue due to some other projects, So i'm posting this job here.
