Thanks for the feedback guys.
It seems like I will go with creating such page. I'm still in the stage where I take on almost any jobs like events, portrait, commercial etc. So for this sort of photography is quite strait forward in term of equipment used for the job, time and post processing, so it is sort of easy to define some sort of package. I guess if I reach a point where I will be doing only advertising and some high profile portraits, perhaps through an agency, then the price/packages option won't be very appropriate. Costumers here in UK, at least in my experience, do not appreciate photography as business, everyone who eventually will get in touch says that don't have much money to spend. It is some sort of carnage here, that is why I was hoping if I create some packages orientated to some sort of industry standard prices for an area such as London, it may help me connect with the sort of customers who like to see the exact thing.
Now for advertising, or photography where there may be some more creativity and equipment involve, also location or probes etc. there will be the need of getting in touch with me for quote.
