I have done a lot of design/coding work for http://muziboo.com http://muziboo.com and http://supportbee.com http://supportbee.com While it may not be possible for you to be the best designer and programmer for your company, you can learn enough to be able to start from an idea and build a MVP and get some customer traction. At that point, you can start hiring experts. No point hiring experts during the validation phase. As long as you can code and make acceptable (read contemporary) designs, you should be able to validate your ideas and bring in some traction on your own. Even when I am hiring for my early stage startup, I would prefer people who can do a little bit of both.
