A couple more thoughts/suggestions. First, you really should consider making a backdrop for when you take pictures of your own work. This can be as simple as a heavy flat bedsheet, or some nice material from the fabric shop. Seeing the clutter and work stations in the background is very distracting to a customer (as a florist, you probably don't notice it--you are too busy focusing on the flowers), but think as a consumer would. It screams "farmers market" and not "professional florist" like you want it to.
Also, i would carefully consider positioning yourself as the "cheap florist" and instead position yourself as the "best value" florist. Instead of having the cheapest prices, I would come just under your competition. For example, your dozen red roses vase is $50. Nelson's Flower Shop (appears to be your closest competition) is $63 for the comparable product. Instead of undercutting them by $13, raise your price to $59.99. Then with some longer stem roses (or more strategic cuts), better filler etc, you could easily make an arrangement that looks twice as big as your competitions AND make more profit for yourself. At that point it would be a win-win. Customers that are looking for the cheapest flowers, will still come to you--you will be cheaper--and those customer generally only need a buck or two to convince them. Customers that are looking for the nicest arrangement for the money, will come to you as well--your arrangement is larger and prettier. Suddenly you have transformed from the cheapest to the "best value".
Compare Nelson's

https://www.alwaysdistinctive.com/distinctiveoccasions/product-info.php?pid5.html for a great example.
This industry is all about value to the customer--and value is more than price. Its quality, design, price and service all bundled into one package. If a competitor falls short on design, then you can leap right over them, set your price higher than them and STILL have the "best value". Compare Nelson's half dozen roses

to Bosses half dozen roses (hope you don't mind Boss)

The presentation easily makes it worth the extra $2.95!
That being said, I know how difficult it is to get your website to where you want it. Mine needs a total overhaul, and if all goes well, it will be happening very soon! Spend some time and look around at fellow chatters. There are alot of members on here with GREAT websites. (not WS garbage). I know I have been spending alot of time seeing what I like and don't like from other sites so that my new site will be the best it can possibly be!
Looks like you have a great start and are headed down the right road.....now its all a matter of fine tuning to get to where you want to be!
