html5 canvas ,php,mysql work

Bid if you have worked in HTML5 canvas & php. I just need 4 small points 1. I need to login > then load my design [which is saved in db] from a dropdown > and press a button to save image on server I need to do this from a url or you can call it from a API, because i want to do this from another script 2. Once the image is generated, show it and save its url in the table along with my insert query. 3. When i add text on canvas it expands on both sides, i want it to expand on right side or on left side only. 4. i want a button on page to zoom in / zoom out canvas for easy viewing and working. I have few options in my canvas, i need to switch it off aswell. I have limited budget, bid if you are looking for a genuine review.
