Looking for google ads expert

I have a shopify drop shipping store that is fairly new (about 6 months) . I have already been running google shopping ads for a few months, and I have been losing money. Before that I ran google search ads and lost even more money! I am considering giving up and just not running any google ads at all. But I am just going to first investigate if there is any possibility that getting professional help would benefit the situation. My google ads budget has been 300 usd per month up until now. Of course I don’t want to increase this budget since already my ads are failing. In the past month I only got only $380 of sales. But the cost of goods sold was approximately $250. So obviously I am losing money. I think that for my particular business, shopping ads are more likely to succeed than search ads. Can you tell me is there any realistic hope that I can made my ads profitable if I use your service? And how much are your fees? Is there some possibility that I would actually end up profitable after everything? Please let me know if you have any comments. My ecommerce website is in health and beauty.
