My suggestion would be that since you are a single founder, the best would be to finish the very minimum viable product that can attract your potential investors. if you think a graphic design is required, then do it. You can outsource logo design cheaply to Asia. Logo design would be something that is more on creative side, imagination doesn't require education, so everyone is a genius if they can pour their imagination into black on white, vs if you are thinking of outsourcing technology development.

as for large server, have you look into AWS? Amazon Web Services is an excellent server solution, Yelp is using AWS. I read somewhere that one of the things that Facebook regrets is that they invest on their own data center vs doing a cloud like in AWS.

I looked into AWS, but I think in the end I would have to have my own server that I can manage. Thanks for your insight.

Doing the server thing yourself? You will be getting into a whole different ball game with your ISP! And that requires a decent revenue stream.

Please take the advaice, even the biggest players out there are using AWS, it's just a far simpler solution for a startup.
