Website Api synch and website full product update

We require supplier Api synched to website for certain information also convert our spreadsheet for upload to woocomerce/Wordpress website the site has been modified the spreadsheet we use is not the same format as woo commerce and it must synch with api stock control on the site as well etc we can supply original spreadsheet from when site was built as we have many product variables and also search options plus a tweak in a couple of products for client ordering options and charging - there is a strict deadline and you must adhere to the timescale. You must be able to utilise woocomerce spreadsheets and variables and also understand synching api . You will need to work on a staging site as we are live website . The changing our spreadsheet to format for upload apparently is the hard bit so please make sure you are fully capable of addressing this . There is a strict time line of 30-days if you cannot achieve do not take the work on as we will not pay any funds until completion due to time wasters that were also from here that took money and never completed . So payment on completion and 30 days deadline if you have any questions ask also if you are based in India we are no longer dealing with anyone there as of the issues last time so no applicants from India at all you will not be considered . Blame the two people last year that took money and did no work !!!!
