Should I switch to Vanguard?

I have a solo 401k for my side business, looking to contribute about 15k yearly to it. I am 31 years old, plan currently has about 19k in assets. I also have about 14k in my full time employers plan that I am putting 9k a year in including my employer match. Total is about 24-25k in retirement savings yearly between both plans, currently have about 33k in assets between both plans. Got started a little late due to grad school and loans but starting to get rolling now. Total income between both jobs is about 180k year.

My question is this: I had a patient who is an advisor who set me up in my solo401k through invesco. I am into the following funds:
INVESCO GOVT MONEY MARKET - CASH RESERVE
INVESCO EUROPEAN GROWTH FUND -CLASS A
INVESCO ASIA PACIFIC GROWTH FUND - CL A
INVESCO SMALL CAP DISCOVERY FUND-CLASS A

I don't know a lot about reading the report sheet on individual funds, but looking at the rates of return over the past 5 years, 1 year, etc none of them have done very well at all, and actually seem to have performed badly. Don't know where to find expense ratios or what is a good amount, but i saw that one of them is like 1.5%. I know Vanguard offers much lower fees, seems to have performed much better, and seems to have a great interface to use.

The guy has now kind of become a friend although he is MUCH older than me, and I feel stuck. He is a patient and I see him every few months, has referred other patients to me, etc. I don't talk to him too often, but he checks in every now and then to see how me and my family are doing, seems to have taken a genuine interest in my life and is a little bit of a mentor when we talk. Am I getting fleeced? Are these funds ripping me off? Any input is appreciated. My balance is low enough to where it is not going to have a huge effect on my future, but I am starting to do pretty well and want to tighten up a bit moving forward.
