I'd prefer charging hourly for such a project (20 USD/hr) I believe that such projects come up with sometimes complex or sometimes easy modifications, or sometimes they are even advanced. Simple modifications or improvements are never a problem, but when it's about complex and advanced level modifications, fixing bugs, or making adjustments in them may lead to some other problem which we may call a Regression bug. Hence it would be better if you allow us to go for an hourly rate. (To maintain a better client-relationship with you, and also to avoid conflicts later on regarding the timelines) We are a team of experts working in the field of web+ mobile development since 2010, helping start-ups + enterprises, or individuals to turn their visions into reality as per their expectations, understanding their needs, their budget, scope, and deadlines. Waiting for at least an initial conversation with you. (Discussion may lead us further to work together I believe) :) Regards, Sapphire.
