Looking for App Testing and Development

I have an unlisted "working" Shopify app that is written in Laravel and is relating to Couponing and uses the discounts API (I coded it) .  I would love to have a skilled PHP/Laravel developer (no agencies please) look at it, test it and help me make final changes to get it approved based on some Shopify feedback already received.  It also connects to a Chrome extension app which I developed.   I can share the link to have a look via private message etc. thx  Chris.
