Photoshop (on-going needs) - for Unique Energy Bars Brand

Hi, we need someone that is very advanced in Photoshop and has a designer eye. We want someone good that will not spend hours on a task that may sometimes only take few minutes. We have regular very simple needs to improve the light, add text to pictures, bundle images etc..These will take you few minutes if you know the software. We will also have needs to improve our current social media header pictures [see [login to view URL] and @btcbars on social media] + create new pictures using several pictures, adding text on request. We sell on Amazon and we need some WOW images. See an example of what we could ask- scroll down to the large picture with the landscape/ text - we are expecting to have several jobs similar over time. https://www.amazon.com/Manukora-Manuka-Honey-UMF-250g/dp/B017TRQYJM/ref=sr_1_1_a_it?srs=11024013011&ie=UTF8&qid=1475299331&sr=8-1&keywords=manuka This is more than simple photoshop work, it needs to look good, we are building a brand. You need to have 'the designer eye". The better you will be the more work we will give you :-) We would also welcome some with force of proposition i.e: oh I have seen this, I think it could fit your brand...It will tell help if you have an interest for a product like ours - it may help your creativity. The best is to pay by task and agree upfront on price for each task. We may start by very little tasks then 'grow together' ;-) We want someone we can rely on when needed, not a one off. We also needs someone good in english so that we can communicate easily. PLEASE SHARE YOUR WORK SO WE CAN SEE/CHOSE. Thank you. Valerie
