cart and other fixes on woocommerce wordpress site

its [login to view URL] , about half of my customers cant checkout, and my bounce rate is bad. it seems to be mostly phones where issues arrise. i ot tons of amp errors too. 1]1 want to upgrade wordpress plan to the ecommerce one.. tried but cintent became all messed up. SO ON A SUN, HOPE THIS ONE FEW DAYS, I WAILL UPGRADE, YOU WILL PUT IT ALL BACK IN PLACE, I ALSO WANT A PAID THME MADE TO WORK WELL ON PHONES. most important of all the cart needs to work even if they have an iphone ... if u have to, use a bew cart... i have feeling theme/upgrade may fix cart... stop and check in after we owe $250, fixing csrt is #1, therres lots more but depending, ill spend $600 but thats bit much. ill pay the $33/h u said on your profile. any plugin conflicts.. we need the "booster" one so we can set our own payment typesand own shipping types. upgrading may eliminate the need for booster.. 1) cart is rarely working,seems to be AMP/Phone issues i think 2) new theme , paid or free dont care but must be great with amp 3)on a sunday i'll upgrade wordpress plans to "ecommerce" and you please fix all the jumbled up content back to look good. 4] any other amp problems or plugin conflicts.. i do need the "booster" plugin but upgrading my wordpress plan may provide the options that booster does now..not sure 3] i have the same product listed many times,once for each amount of product... silly, so please put a way to select quantity(altering price obviuously) on each products page, so that each product is listed once. 5] i just installed the ups plugin, if you could help integrate it that would be great.
