Hi there. This sounds like an interesting job. If you take a look at my portfolio you will see a selection of my design work. I run a PC, so unfortunately I can't use Sketch 3. But that said I prefer to do all my design work in Illustrator anyway. I hope this will not be a huge hurdle. Giving you a fixed price suits me a lot better than an hourly rate, also it probably allows you to on sell the service easier to your clients. I also have around 10 years experience as a web developer, but nowadays I prefer to just design, as it is easier for me to freelance design work than freelance web dev. Well there is a lot to discuss about the job, but before all that I suppose it is best to first see if you are interested in my skills. The web design items in my portfolio might be a bit dated now, as they are old from memory. But hopefully the strength of my other design lets you know my skills. I should have other samples that may be more relevant if you wish to see them. Anyway, I wish you all the best. Regards, Joshua.
